The YLC-2 radar (domestic designation: LLQ303, formerly known as 385) is a three-dimensional main guidance and surveillance
radar
Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, w ...
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
Moving target indication (MTI) is a mode of operation of a radar to discriminate a target against the clutter. It describes a variety of techniques used for finding moving objects, like an aircraft, and filter out unmoving ones, like hills or tree ...
