Abstract

The invention relates to a radar image motion compensation method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining first motion information of a radarplatform and an acquired radar image; re-estimating the first motion information to obtain second motion information; updating the motion trail of the radar platform by using the second motion information; and compensating the radar image by using the motion trail. The embodiment of the invention can improve the precision of the radar image.

Description

technical field [0001] The present disclosure relates to the technical field of radar, and in particular to a method and device for motion compensation of radar images, electronic equipment, and a storage medium. Background technique [0002] Environmental factors such as the performance of the carrier equipment and the air flow in the air will affect the stability of the radar platform, causing the radar to deviate from the ideal trajectory. When the trajectory offset error of the carrier platform is too large, it will cause the blurring of the scene target. Therefore, in order to obtain high-quality SAR (Synthetic Aperture Radar, synthetic aperture radar image), accurate motion error compensation must be performed. If the trajectory of the radar platform can be accurately estimated and precise motion compensation can be performed, the quality of imaging can be improved. [0003] Airborne SAR motion error compensation technology mainly includes motion error compensation b...
