Abstract

Abstract

Circular-Scan SAR is mainly used for scene matching in the precision-guided missiles, where geometry accuracy is very important. However, due to errors introduced by the GPS/IMU, it remains somewhat geometric distortion after geometric distortion correction based on the GPS/IMU data. This paper analyzes the impact of the error of scan angle and aircraft height and aircraft velocity on the image quality. Meanwhile, approaches to correcting these errors based on measured data are presented. Experiments carried out on measured data confirm the validity of the analysis and the feasibility of the compensation scheme.
