AbstractThis 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. The upgrading include the two-channel dechirping-on-receiving receiver and the data sampling and recording subsystem where high-speed optical transmission technique is used. We use two arbitrary waveform generators in the system, one for transmitting and another one for receiving, which provides us a great convenience for transmitting / receiving design. We briefly introduce the system design as well as discuss about the pulse compressing algorithm. In the outdoor experiment, buses, trucks and trains were taken as the ground moving targets to image and high-resolution images were obtained. The micro-Doppler phenomenon resulted from the rolling wheels is investigated. © 2015 IEEE.
