JY-27 “Wide Mat”

JY-27 radar of the Chinese manufacturer CETC is a fully solid-state and fully coherent long-range early warning system. It is designed and developed to provide early warning information and detect low-observable air targets in so-called “Stealth Technology”. Besides, it provides the early warning information for weapons system as well.

The newer one antenna design is clearly influenced by the 1L13 Nebo SV “Box Spring” and 1L119 Nebo SVU. The radiating elements are horizontally polarized.
