A 3 mm-wave battlefield surveillance radar for the mini-UAV

This paper describes the configuration, operation principles and the performance of battlefield surveillance radar for the mini-UAV (unmanned vehicle). It is a light-weighted, coherent pulse-Doppler radar, which operates in both high resolution ground mapping (HRGM) and moving target detection (MTD) modes. The transmitting pulse power of the radar is 35 W, while the range resolution is 4.5 m, and the azimuth resolution is 0.4/spl deg/. It can provide a forward azimuth coverage of /spl plusmn/20/spl deg/. The range of detecting a jeep is 2/spl sim/3 km. The radar can be used for reconnaissance and surveillance missions with good performance even in adverse weather conditions or a smoky battlefield environment. It is especially suitable for the operation on an unmanned surveillance air vehicle.
