JY-27 “Wide Mat”

The JY-27 “Wide Mat” is a fully solid-state, fully coherent, long-range early warning air defense radar manufactured by the Chinese company CETC. Operating in the VHF band (240–390 MHz) with an instrumented range of 280 km and a range resolution of 600m, it is designed to detect low-observable air targets, including those employing stealth technology, and provide early warning information for weapon systems. Its newer antenna design, featuring horizontally polarized radiating elements and a 7° beamwidth, shows clear influence from the 1L13 Nebo SV “Box Spring” and 1L119 Nebo SVU radar systems, offering an accuracy of ±150 m in range and ±1º in azimuth.
