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.
