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.
中国反隐身雷达“双子星”亮相中国航展。在本次中国航展上，中国电科14所展出了YLC-8E型高机动反隐身防空警戒雷达和YLC-2E型S波段远程多功能雷达两款反隐身雷达。两款雷达采用不同的技术路线，但都具备强大反隐身能力，堪称反隐身界的“双子星”。
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型雷达为首度公开亮相，该雷达摆脱了传统隐身雷达对低频段/米波雷达的依赖，是目前国际市场上首款非米波的高性能反隐身产品。
YLC-8E: Achieving extreme performance of "meter-wave radars"
YLC-8E：将“米波雷达”发挥到极致
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.
雷达作为战场之眼，是撕开隐身战机“隐身外衣”的关键，在反隐身作战中占据着核心位置。传统上，应对反隐身的主要解决方式是通过频段探测隐身目标，也就是我们常说的米波雷达，因为电磁波波长长，波照射到隐身飞机后会形成“绕射”现象，对探测隐身目标具有天然的优势，这点已经在实践中得到验证。
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.
中国电科14所被外界誉为中国的“反隐身雷达旗舰店”，曾在中国航展上面向国际市场推出了YLC-8B、YLC-8E、SLC-7等雷达产品，这些雷达大都属于我们常说的“米波雷达”。其中，YLC-8B雷达在2016年首次公开后，凭借强大的反隐身性能而被誉为中国反隐身雷达的“旗舰”型号。
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的升级型号，低频段雷达本身具有反隐身能力，但是过去的雷达由于尺寸大，机动性弱，自动化水平低，难以适应新形势下反隐身作战的要求。YLC-8E完全克服了这些缺点，成为全球首款UHF机动式隐身目标探测雷达。
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.
据了解，通过使用新一代半导体技术、提升单通道发射功率以及先进的技术体制和算法，YLC-8E成功实践了频段和能量反隐身设计并重的反隐身雷达设计理念，确保了强大的反隐身能力，是一款将传统米波雷达设计和性能发挥到极致的先进反隐身雷达产品。

YLC-2E: Non-meter-wave anti-stealth radar
YLC-2E：非米波反隐身雷达
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.
时至今日，频段/米波反隐身雷达的优势依然存在，除了技术上的“先天优势”，成本也相对较低，是反隐身预警体系中不可或缺的一环。但米波雷达因为物理限制，在探测精度上存在一些不足。为此，14所科研人员尝试摆脱“反隐身靠米波雷达”的思想桎梏，突破反隐身雷达对低频段的依赖，推出了目前国际军贸市场上的首款非米波反隐身雷达——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虽然没有YLC-8E等雷达的频段反隐身优势，但能量优势更为明显。在相当于半个标准羽毛球场面积的雷达天线阵面上，可以布置数量庞大的大功率雷达T/R组件，经过优化设计结合极高的能量应用效率，能够让雷达天线产生令人惊叹的能量，成为能量反隐身的硬件基础。在硬件基础之上，YLC-2E采用智能算法软件，对雷达探测目标进行最优化的调度，确保雷达能够在广袤的天空中识别出微小的隐身目标，并且具备强大的抗干扰能力。简而言之，YLC-2E通过强劲的雷达能量和先进算法获得了强大的反隐身能力，两者缺一不可。
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.
据介绍，YLC-2E雷达探测效果与YLC-8B/YLC-8E这类“传统”频段反隐身雷达相当，具备相近的隐身目标探测距离。
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.
专家表示，YLC-2E与YLC-8B/YLC-8E这类频段反隐身雷达并不是替代关系，而是互补关系。米波等低频段雷达的成本具有优势，而YLC-2E则具备更为全面的性能和多样化用途，可以更高效地支撑起反隐身作战体系。
