The solid state radar introduced in this report mainly has advantages of "long life"，"maintenance cost reduction"，and "target detection performance enhancement in a clatter" compared with the magnetron radar. The solid state radar which JRC has developed this time consists of two units which connected MFD（Multi Function Display） as a display unit to the antenna. And the mass has satisfied the weight saving reduced about 50% compared with a conventional model（12-ft model） by the antenna reduced it in size and weight and by the high integration of each circuit, etc. Since LD-MOS FET is adopted as a transceiver circuit, it has ten years or more of life. Moreover, the wide dynamic range of the system has improved in detection performance as compared with the conventional equipment with respect to the performance.
