| Abstract: | This paper describes an airship borne SAR developed at the Institute of Electronics, Chinese Academy of Sciences. The airship borne SAR system features high resolution imaging capability of ground targets in the limited area. The function and architecture of the SAR are described in detail. An effective motion compensation method integrated IMU, DGPS and autofocus algorithm is proposed for the low speed airship platform. High quality images formed in the flight tests demonstrate the precision microwave imaging and measurement capacity provided by the airship borne SAR. |
