YLC-2 Radar
From Infogalactic: the planetary knowledge core
The YLC-2 radar (domestic designation: LLQ303, formerly known as 385) is a three-dimensional main guidance and surveillance radar developed by the Nanjing Research Institute of Electronics Technology.
In the mid-2000s, an improved version labeled YLC-2A was deployed to the PLA. Equipped with a new Giga-flops digital signal processor, it is capable of Digital Moving Target Indication (DMTI) and Constant false alarm rate (CFAR) processing. An S-band variation called YLC-2U with similar capabilities was also developed for SAM guidance. Both of these advanced YLC-2 radars have been specifically designed to counter stealth fighters such as F-22, with a claimed range of up to 200km even in heavy ECM environment.
