YLC-4

YLC-4 is a UHF-Band 2-D solid-state, fully coherent long-range surveillance radar which features a built-in test equipment, pulse-to-pulse, burst-to-burst frequency agility, system redundancy for reliability and moving target indicator. In terms of data manipulation, the radar incorporates semi-automatic or automatic target performance extraction and the ability to synthesise, display and (communicate) data from up to four other radars such as height finders and gap fillers.

The antenna uses a squintless feed wich results in verly low sidelobes. The dimensions of the reflector are 16.5 × 7.12 m.
