The JTPS-P11 is a short-range air defense and surveillance radar system, developed by NEC Corporation of Japan in 1986 as the successor to the JTPS-P6. Operating in the X-band (IEEE designation) or I/J-band (NATO designation), it is designed for battlefield and coastal defense applications. The entire radar system is housed within a container, transportable by a 1.5-ton truck, with its antenna mounted on the roof and capable of being elevated up to 4.5 meters via a mast.
