Abstract

A polarimetric Ground Based-SAR system that can achieve continuous scanning is evaluated in this paper. Our laboratory has developed compact and continuous scanning system with a compact VNA and a box type Vivaldi antenna array composed by four Vivaldi antennas. Weight of the VNA is reduced from 22 kg to 3 kg, and we also reduced weight of the antenna from 8 kg to 1 kg in order to develop more compact system. After we developed the continuous scanning system with the VNA and the array antenna, we evaluated effects of continuous scanning in this system. First, we measured a metallic sphere with both of Stop & Go scanning and continuous scanning. After that, we evaluated the difference of both scanning methods by comparing radar images. As a result, we confirmed that there was no significant difference between two scanning methods.
