همه چیز درباره رادارهای ایران/ 3

فناوري چهاربعدی برای شکار پرنده‌های پنهانکار + عکس

تولید داخل بودن انواع رادارهای میانبرد و دوربرد برای ایجاد یک پوشش کامل در نواحی مختلف راهگشا بوده و تمامی مسیرهای ورودی به کشور و شیارهایی که برای نفوذ مهاجمینی چون موشک‌های کروز و تسلیحات هواپرتاب دورایستا استفاده می‌شود دائما زیرنظر خواهد بود.
به گزارش گروه دفاع و امنیت مشرق، هر چند ساخت رادارهای تاکتیکی و برد متوسط برای رفع نیاز سریع و مقطعی لازم است اما یک مجموعه پدافندی هر چه زودتر از وجود تهدیدات و کم و کیف آنها مطلع و آگاه شود فرصت بیشتری برای پردازش شرایط و اتخاذ بهترین تصمیم دارد. برای این منظور رادارهای دوربرد و قابل تر و طبیعتاً پیچیده و گران قیمت تری مورد نیاز است. تهدیدات مدرن امروزی که عموماً چه در ابعاد کوچک باشند و چه بزرگ از فناوری های پنهان کاری راداری(رادار گریزی) تا حد ممکن بهره مند می شوند بر پیچیدگی کار رادارهای برد بلند می افزایند.

میزان داده های دریافتی از فضای بزرگتر طبعاً بیشتر است و پردازش آنها و حذف اطلاعات غیر مفید(بازتاب های راداری ناخواسته) را نیز باید به موارد فوق افزود. بنابراین رادارهای دوربرد برای ایفای نقش بسیار مهم «هشدار زود هنگام» در این روزگار باید از فناوری بالایی نیز برخوردار باشند. باید در نظر داشت به طور معمول به رادارهایی با برد بیش از 300 کیلومتر رادار دوربرد گفته می شود.

همانطور که در قسمت های پیشین گزارش گفته شد برای غلبه بر ویژگی های پنهانکاری هواگردهای مدرن یک راه استفاده از رادارهای با طول موج بلند نظیر VHF و HF است. هر چند به دلیل همین طول موج بلند که در رده متر است خطایی در رده چند ده تا چند صد متر در موقعیت یابی دقیق هدف ایجاد می شود اما با توجه به نقش این رادراها در شبکه پدافندی که تشخیص اولیه هدف است این خطا مشکلی بوجود نمی آورد و در عوض اهدافی به کوچکی بمب های هدایت شونده بالدار دورایستا نیز کشف و مسیریابی می شوند.

پس از پایان جنگ تحمیلی و فرارسیدن دوران بازسازی تجهیزاتی نیروهای مسلح، علاوه بر استفاده از راداهای سامانه های دوربرد موشکی به منظور ایجاد پوشش دوربرد، راداهای مستقلی نیز تأمین شد از جمله رادار چینی JY-14 که در بخش اول گزارش به آن پرداختیم. اما از جمله رادارهای سامانه های دوربرد در ایران باید به اسکوارپیر و P-14 در سامانه پدافند هوایی موشکی اس-200 به ترتیب با بیشینه برد تا 500 و تا 600 کیلومتر اشاره نمود که استقرار این سامانه در نقاط مختلف کشور پوشش دوربرد مناسبی را به عنوان اولین حساسه نیروی پدافند هوایی کشور فراهم کرده است.

اما شاید بهترین و پیشرفته ترین رادار اعلام شده در مجموعه دفاع هوایی کشور، رادار روسی «نبو» باشد. نبو یک رادار کششی برد بلند و مخصوص هشدار زودهنگام هوایی است که در باند وی-اچ-اف کار می کند. این رادار تمام دیجیتالی به عنوان یکی از پیشرفته ترین رادارهای زمین پایه جهان که حضور آن در ایران تعجب کارشناسان خارجی را نیز برانگیخت با استفاده از فناوری های پیشرفته ای چون آنتن آرایه کاوش الکترونیکی فعال(AESA) و البته با المانهایی در فرم یاگی و هدایت الکترونیکی امواج کار برای شناسایی اهداف، رهگيري و تعقيب زاويه اي تک پالس ها را نیز به انجام می رساند و قابليت تصوير سازي 4 بعدي براي بی اثر کردن اخلالگرهاي ديجيتال را دارد.


رادار نبو که شبیه به نمونه موجود از آن در ایران است؛ 84 آنتن یاگی در این نبو به کار رفته

نبو قابلیت شناسایی طیف وسیعی از هواگردها شامل بیش از 100 هداف آیرودینامیک، موشک های بالستیک و کروز را در برد و سقف پرواز کوتاه تا بلند دارد. قابلیت های مقاومت در برابر جنگ الکترونیک دشمن به اذعان منابع غربی بسیار بالا است. همچنین نحوه عملکرد این رادار مقاوت بسیار بالایی در برابر موشک های ضدرادار فراهم کرده و تا حدودی در عملکرد آنها ایجاد اختلال نیز می نماید. برای این رادار برد 350 کیلومتر و سقف پرواز 100 کیلومتر اعلام شده است.

امروزه نبو نیز از پیشرفت های بومی کشور بی نصیب نمانده و توسط متخصصان داخلی در برخی زمینه ها در حال طی کردن فرآیند بهسازی است.


مطلع الفجر-1

برای رفع نیاز کشور در سطح مورد نظر، برای مدت طولانی، جلوگیری از ایجاد وابستگی، و پوشش تمام کشور در هر زمینه شاید بهترین راه، جز اتکا به توان داخلی نباشد. از اینرو همانطور که در بخش های پیشین گزارش گفته شد برنامه ساخت رادارهای دوربرد نیز در کشور در دستور کار قرار گرفت که رادار ملی به عنوان اولین رادار ایرانی راداری دوربرد نیز بود.

اما نیازهای جدید متخصصان را به سمت ساخت رادارهایی با تحرک مناسب و بالا هدایت کرد که رادارهای میانبرد و دوربرد مطلع الفجر از جمله آنها هستند. لازم به ذکر است در زمینه رادارها برد مورد نظر برای دوربرد خطاب کردن یک سامانه در حدود 400 کیلومتر به بالا بوده و بردهای کمتر از آن تا حدود 30 کیلومتر به طور معمول توسط مسئولان امر به عنوان میانبرد معرفی می شود.

رادار مطلع الفجر-1 از اولین نمونه های رادارهای داخلی با توانایی مناسب در کشف اهداف پنهانکار است. وجود این رادار که در زمره رادارهای با برد متوسط به بالا قرار می گیرد در باند VHF کار می کند و محصول تفکر استفاده از کلیات یک سامانه موجود برای رسیدن به سامانه ای پیشرفته و قابل، با اتکا به توانمندی نیروهای داخلی در زمینه های پیشرفته ای چون مخابرات، الکترونیک و رایانه است.

Kremlin Seeking Naval Bases Abroad

Kremlin Seeking Naval Bases Abroad - January, 2011

Moscow is not concealing its strong desire to play a greater political role in the Middle East and to have a greater naval presence in the Mediterranean Sea. Establishing a naval presence in strategic seaports throughout the world is more-or-less a prerequisite for any aspiring global superpower. The socioeconomic turmoil that followed the collapse of the Soviet Union forced Moscow to abandon its strategic naval bases in Cuba and Vietnam. Despite the chaos of the post Soviet years, however, Moscow continued to keep a presence, albeit a small one, in Syria's second largest port city of Tartus. It is becoming increasingly clear now that Moscow is interested in increasing its military presence in Syria. Russia's growing presence in Syria may actually explain why Syria has not yet had its sovereignty grossly violated by the Anglo-American-Zionist alliance. Moreover, in an interesting turn of affairs, after spending years kissing Washington's ass and feet in hopes of receiving modern weaponry, Lebanese officials have finally come to their senses and traveled north recently to meet with the Russian Bear. The following news articles are pertaining to these recent developments. The article posted at the bottom of this page was taken from the Jerusalem Post several years ago. The article in question refers to an interesting incident that is said to have taken place between Russia and Israel in 1996.

Georgia will seek close cooperation with both Russia

Georgia will seek close cooperation with both Russia Georgia will seek close cooperation with both Russia and Western powers, billionaire tycoon Bidzina Ivanishvili said on Tuesday, as his opposition coalition headed for election victory.

“It is very difficult to have many strategic partners, but we have to try and do this,” Ivanishvili told journalists. “If we can build a democratic state, I believe we will have a genuine opportunity to forge good relations with NATO and Russia.”

President Mikheil Saakashvili conceded earlier on Tuesday that his ruling United National Movement (UNM) had lost to Ivanishvili’s Georgian Dream coalition in crucial parliamentary polls after what he called an “emotional and tense” election campaign.

The elections took on particular importance in the light of a law passed in 2010 transferring the majority of the president’s executive powers to the prime minister. The law comes into force from 2013, when Saakashvili’s second term ends.

Saakashvili came to power in 2003 after a popular revolt against a regime headed by former Soviet foreign minister Eduard Shevardnadze. He was soon praised by Western powers for his democratic reforms and proved a staunch US ally – contributing the third largest contingent of troops to Iraq.

Historical evidence indicates Diaoyu Islands part of China

The National Library of China on Monday presented historical documents, atlases and ancient journals regarding the Diaoyu Islands and their affiliated islets in the East China Sea.

The National Library of China on Monday presented historical documents, atlases and ancient journals regarding the Diaoyu Islands and their affiliated islets in the East China Sea.

The documents are intended to demonstrate that China discovered the Diaoyu Islands at the beginning of the 15th century, as well as put them under its jurisdiction as affiliated islets of Taiwan.The central government folded the Diaoyu Islands into the defense scope of east China's Fujian province, the documents show.In 1885, the Meiji administration of Japan found the islands through an investigation by Okinawa authorities in 1895.It is "a sheer historical lie" for Japan to claim sovereignty over the Diaoyu Islands based on the principle of "first come, first served," according to a statement from the library.The "Record of the Imperial Envoy's Visit to Ryukyu" displayed at the exhibition represents the earliest Chinese document to record the maritime boundaries of China.

IRGC Announces Production of Drone with Missile Capability

IRGC Announces Production of Drone with Missile Capability TEHRAN (FNA)- Commander of the Islamic Revolution Guards Corps (IRGC) Major General Mohammad Ali Jafari announced that his forces have built a new type of military drone with missile capability.

Collective destructionism of Armenians - August, 2012

Collective destructionism of Armenians - August, 2012

As the presidential election in Armenia gets nearer, the young republic's so-called political opposition is again preparing to cause unrest. While their approach and tactics will vary somewhat, they will be united in the hope that by putting pressure on the entrenched government and by disseminating poisonous propaganda, the masses will eventually rise-up against their leadership, similar to what happened in early 2008 when Levon Petrosian's and his gang of criminals attempted their ill fated revolution. 

The intent of this blog entry is to help open eyes and prepare the reader for the coming election season in Armenia, which promises to be very interesting to say the least. 

Below this commentary I am presenting you the work of a good comrade. His work is essentially about the dangerously negative mood presiding inside Armenian society today and it is aptly called "Collective Destructionism". Below his excellent work I have also posted several very rare voices of sanity and objectivity. Please read them all. We need to be informed of the political dangers that our newly formed republic faces, and armed with this information we need to fight against the negativity and the destructive criticism that is being engineered by Armenia's Western led, funded and/or inspired political opposition.

The U.S. Navy destroyer USS Porter suffered significant damage after colliding with an oil tanker in the Strait of Hormuz on Sunday.

 The USS Porter is an Arleigh Burke-class destroyer that is part of the 5th fleet. That particular class of destroyer runs about $1.1 billion ($321.9 million for the ship; an extra $778 million for the weapons systems). They carry about ninety missiles of different types, and carry torpedo, helicopter, and gun weapons systems as well. You’d think a bit more of that money would have gone into adequate navigational systems.

The U.S. Navy destroyer USS Porter suffered significant damage after colliding with an oil tanker in the Strait of Hormuz on Sunday.

The USS Porter was passing through the Strait of Hormuz into the Persian Gulf.

The Japanese-owned, Panamanian flagged tanker M/V Otowasan was coming the other way, just entering the Strait of Hormuz, and the two crashed into one another.

The shipping lanes are very narrow, about two miles wide in each lane.  The crash left a hole in the side of the destroyer but no injuries were reported.

The damage is all above the water-line, so there is no danger that the ship will sink, but likely sustained water damage because the fire control system would have activated.

After the collision USS Porter headed to a port called Jebel Ali in the UAE.

Cold War II - Heralding the Rise of a Bipolar World

Cold War II - Heralding the Rise of a Bipolar World - May, 2012

“Today we are witnessing an almost uncontained hyper use of force – military force – in international relations, force that is plunging the world into an abyss of permanent conflicts. As a result we do not have sufficient strength to find a comprehensive solution to any one of these conflicts. Finding a political settlement also becomes impossible. We are seeing a greater and greater disdain for the basic principles of international law. And independent legal norms are, as a matter of fact, coming increasingly closer to one state’s legal system. One state and, of course, first and foremost the United States, has overstepped its national borders in every way.”

- President Vladimir Putin at the Munich Conference on Security Policy (February 11, 2007)

"As soon as one side comes under the illusion that it is invulnerable to a strike from the other, there immediately arise both a number of conflicts and aggression... Not because America is by definition an aggressive country, but because it is a fact of life. There is no way around it. And this worries us."  - Presidential candidate Vladimir Putin during a nationwide televised interview in Moscow (March 2, 2012)In my opinion, the historic comments made by Vladimir Putin at the Munich Conference back in early 2007 signaled the official commencement of Moscow's reemergence as a global leader and its belligerence towards the political West. And Vladimir Putin's comment made on nationwide Russian television in early 2012 signaled that Moscow's belligerence will surely continue for the rest of this decade. Nevertheless, ever since those powerful words were resonated around the world back in 2007, the West has not missed any opportunity to attack Vladimir Putin. Five years ago Putin verbally signaled to the West that Russia was back on the international stage as a major political player and as the long-awaited balancing power the global community desperately needed. Four years ago, Moscow crushed the Western-backed Georgian military to make its point perfectly clear. And this year Putin is back to finish some unfinished business.

Kaliningrad: Russia’s anti-shield base

Kaliningrad: Russia’s anti-shield base

On Thursday, General Nikolai Makarov, Russia’s most senior military commander, warned NATO that if it proceeded with its missile defence system in Europe, Moscow would use force against it. According to Makarov, Russia may counter NATO deployment by stationing short-range Iskander missiles in the Russian Kaliningrad exclave, on the Baltic Sea. “The deployment of new strike weapons in Russia’s south and northwest - including Iskander systems in Kaliningrad - is one of our possible options for destroying the system’s European infrastructure,” the General said, while speaking at a conference in Moscow on anti-ballistic missile policy.
