This paper introduces our recently upgraded Ka-band two-receiving-channel radar system, which adopts stepped-frequency chirp signal (SFCS) and the signal spans 2GHz bandwidth. Both indoor and outdoor experiments have been carried out. A truck driving on a road was taken as the ground moving target to image and high-resolution images were obtained. The micro-doppler phenomenon resulted from the rolling wheels is investigated.
