YLC-2 Radar
Encyclopedia
The YLC-2 radar 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.
Radar
Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio...

, it is capable of Digital Moving Target Indication
Moving target indication
Moving target indication is a mode of operation of a radar to discriminate a target against clutter. In contrast to another mode, stationary target indication, it takes an advantage of the fact that the target moves with respect to stationary clutter. The most common approach takes advantage of...

Constant false alarm rate
Constant false alarm rate detection refers to a common form of adaptive algorithm used in radar systems to detect target returns against a background of noise, clutter and interference.Other detection algorithms are not adaptive...
