Airship SAR System for Precision Microwave Measurement of Ground Targets

摘要

摘要: 针对地面目标微波散射特性的高分辨率成像测量需求，该文给出了一种基于飞艇平台的合成孔径雷达(SAR)测量系统。介绍了飞艇SAR系统的构成和功能，详细探讨了合成孔径雷达的技术性能，提出了针对飞艇慢速飞行平台所采取的结合IMU，DGPS和自聚焦的成像和运动补偿方案。通过实际飞行试验，验证了飞艇SAR对目标高分辨率成像测量的可行性。

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.
