BEIJING, Nov. 14 -- The "binary stars" of China's anti-stealth radars were unveiled at the 15th China International Aviation and Aerospace Exhibition (Airshow China). At the airshow, the 14th Research Institute of China Electronics Technology Group Corporation (CETC) displayed two anti-stealth radars including the YLC-8E high-mobility anti-stealth air defense warning radar and the YLC-2E S-band long range multi-role radar. Though designed through different technical routes, the radars both have powerful anti-stealth capabilities, earning them the fame of the "binary stars" in the field of anti-stealth radars.

中國反隱身雷達(dá)“雙子星”亮相中國航展。在本次中國航展上，中國電科14所展出了YLC-8E型高機(jī)動反隱身防空警戒雷達(dá)和YLC-2E型S波段遠(yuǎn)程多功能雷達(dá)兩款反隱身雷達(dá)。兩款雷達(dá)采用不同的技術(shù)路線，但都具備強(qiáng)大反隱身能力，堪稱反隱身界的“雙子星”。

The YLC-2E radar made its debut at the airshow. Getting rid of the reliance on low frequency band or meter-wave radar like traditional stealth radars, it becomes the first non-meter-wave high-performance anti-stealth product in the international market.

其中，YLC-2E型雷達(dá)為首度公開亮相，該雷達(dá)擺脫了傳統(tǒng)隱身雷達(dá)對低頻段/米波雷達(dá)的依賴，是目前國際市場上首款非米波的高性能反隱身產(chǎn)品。

YLC-8E: Achieving extreme performance of "meter-wave radars"

YLC-8E：將“米波雷達(dá)”發(fā)揮到極致

As the eyes on the battlefield, radars play a core role in anti-stealth operations as the key to penetrating the "stealth cover" of stealth fighters. Traditionally, the main solution to counter stealth technology is to detect stealth targets through frequency bands, which is commonly referred to as meter-wave radar. Because of its long electromagnetic wavelength, the wave will form a "diffraction" phenomenon after striking the stealth aircraft, bringing it the natural advantage of detecting stealth targets. This feature has been verified in practice.

雷達(dá)作為戰(zhàn)場之眼，是撕開隱身戰(zhàn)機(jī)“隱身外衣”的關(guān)鍵，在反隱身作戰(zhàn)中占據(jù)著核心位置。傳統(tǒng)上，應(yīng)對反隱身的主要解決方式是通過頻段探測隱身目標(biāo)，也就是我們常說的米波雷達(dá)，因為電磁波波長長，波照射到隱身飛機(jī)后會形成“繞射”現(xiàn)象，對探測隱身目標(biāo)具有天然的優(yōu)勢，這點已經(jīng)在實踐中得到驗證。

The 14th Research Institute of CETC, hailed as China's "anti-stealth radar flagship store", has introduced to the international markets its YLC-8B, YLC-8E, SLC-7 and other radar products, most of which are the commonly called meter-wave radars. Among them, the YLC-8B, after making its debut in 2016, is known as the flagship model of China's anti-stealth radars with its powerful anti-stealth performance.

中國電科14所被外界譽(yù)為中國的“反隱身雷達(dá)旗艦店”，曾在中國航展上面向國際市場推出了YLC-8B、YLC-8E、SLC-7等雷達(dá)產(chǎn)品，這些雷達(dá)大都屬于我們常說的“米波雷達(dá)”。其中，YLC-8B雷達(dá)在2016年首次公開后，憑借強(qiáng)大的反隱身性能而被譽(yù)為中國反隱身雷達(dá)的“旗艦”型號。

The YLC-8E is an upgrade based on the YLC-8B. The low frequency band radar itself has anti-stealth capabilities, but previous radars have difficulties in meeting the requirements of anti-stealth operations in the new situation due to its large size, low mobility and outdated automation level. The YLC-8E successfully overcame such shortcomings and became the world's first mobile UHF stealth target detection radar.

YLC-8E是YLC-8B的升級型號，低頻段雷達(dá)本身具有反隱身能力，但是過去的雷達(dá)由于尺寸大，機(jī)動性弱，自動化水平低，難以適應(yīng)新形勢下反隱身作戰(zhàn)的要求。YLC-8E完全克服了這些缺點，成為全球首款UHF機(jī)動式隱身目標(biāo)探測雷達(dá)。

It is learned that the YLC-8E has successfully implemented the anti-stealth radar design concept of combining frequency bands and energy anti-stealth designs by means of applying the new generation semiconductor technology, improved single-channel transmission power and advanced technical systems and algorithms, thereby ensuring a strong anti-stealth capability. These strengths make it an advanced anti-stealth radar product that achieves the extreme design and performance of traditional meter-wave radars.

據(jù)了解，通過使用新一代半導(dǎo)體技術(shù)、提升單通道發(fā)射功率以及先進(jìn)的技術(shù)體制和算法，YLC-8E成功實踐了頻段和能量反隱身設(shè)計并重的反隱身雷達(dá)設(shè)計理念，確保了強(qiáng)大的反隱身能力，是一款將傳統(tǒng)米波雷達(dá)設(shè)計和性能發(fā)揮到極致的先進(jìn)反隱身雷達(dá)產(chǎn)品。

YLC-2E: Non-meter-wave anti-stealth radar

YLC-2E：非米波反隱身雷達(dá)

The frequency band or meter-wave anti-stealth radar still has its advantages. In addition to its natural technological advantages, its relatively low cost makes it an essential player in the anti-stealth warning system. Due to the physical limitations, however, meter-wave radars have some deficiencies in detection accuracy. To solve the problem, the 14th Research Institute of CETC tried to get rid of the shackles of the "anti-stealth only by meter-wave radar" concept and eliminate the reliance of anti-stealth radar on low frequency bands. Eventually, it rolled out the first non-meter-wave anti-stealth radar in the international military trade market, the YLC-2E.

時至今日，頻段/米波反隱身雷達(dá)的優(yōu)勢依然存在，除了技術(shù)上的“先天優(yōu)勢”，成本也相對較低，是反隱身預(yù)警體系中不可或缺的一環(huán)。但米波雷達(dá)因為物理限制，在探測精度上存在一些不足。為此，14所科研人員嘗試擺脫“反隱身靠米波雷達(dá)”的思想桎梏，突破反隱身雷達(dá)對低頻段的依賴，推出了目前國際軍貿(mào)市場上的首款非米波反隱身雷達(dá)——YLC-2E。

Even without frequency band anti-stealth advantages like such radars as the YLC-8E, the YLC-2E has more advantages in energy. A large number of high-power radar T/R components can be placed on the radar array surface equivalent to the half of a standard badminton court area, yielding extremely high energy application efficiency through optimized design to enable the radar antenna to produce amazingly great energy, which creates the hardware basis for energy anti-stealth. As for the hardware basis, the YLC-2E uses intelligent algorithm software to optimize the radar's scheduling of target detection, ensuring that the radar can identify small stealth targets in the vast sky and have a powerful performance of anti-interference. In short, through robust radar energy and advanced algorithms, neither of which can be neglected, the YLC-2E achieves powerful anti-stealth capabilities.

YLC-2E雖然沒有YLC-8E等雷達(dá)的頻段反隱身優(yōu)勢，但能量優(yōu)勢更為明顯。在相當(dāng)于半個標(biāo)準(zhǔn)羽毛球場面積的雷達(dá)天線陣面上，可以布置數(shù)量龐大的大功率雷達(dá)T/R組件，經(jīng)過優(yōu)化設(shè)計結(jié)合極高的能量應(yīng)用效率，能夠讓雷達(dá)天線產(chǎn)生令人驚嘆的能量，成為能量反隱身的硬件基礎(chǔ)。在硬件基礎(chǔ)之上，YLC-2E采用智能算法軟件，對雷達(dá)探測目標(biāo)進(jìn)行最優(yōu)化的調(diào)度，確保雷達(dá)能夠在廣袤的天空中識別出微小的隱身目標(biāo)，并且具備強(qiáng)大的抗干擾能力。簡而言之，YLC-2E通過強(qiáng)勁的雷達(dá)能量和先進(jìn)算法獲得了強(qiáng)大的反隱身能力，兩者缺一不可。

The YLC-2E has a detection effect comparable to traditional frequency band anti-stealth radars such as the YLC-8B and the YLC-8E, as well as a similar stealth target detection range.

據(jù)介紹，YLC-2E雷達(dá)探測效果與YLC-8B/YLC-8E這類“傳統(tǒng)”頻段反隱身雷達(dá)相當(dāng)，具備相近的隱身目標(biāo)探測距離。

According to the experts, the YLC-2E is not substitutional but complementary to the frequency band anti-stealth radars such as the YLC-8B and the YLC-8E. The meter-wave and other low frequency band radars have cost advantages, while the YLC-2E has more comprehensive performance and diversified applications, which can support anti-stealth operational systems more efficiently.

專家表示，YLC-2E與YLC-8B/YLC-8E這類頻段反隱身雷達(dá)并不是替代關(guān)系，而是互補(bǔ)關(guān)系。米波等低頻段雷達(dá)的成本具有優(yōu)勢，而YLC-2E則具備更為全面的性能和多樣化用途，可以更高效地支撐起反隱身作戰(zhàn)體系。
