Title:
SAR IMAGING METHOD AND IMAGING SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/191978
Kind Code:
A1
Abstract:
An SAR imaging method, comprising: acquiring an estimated position and speed of a target object, and sending an SAR detection signal and receiving same (101); acquiring, according to the estimated position and speed of the target object, parameters of the relative motion between the target object and a detection radar in at least two continuous moments, the parameters of the relative motion at least comprising a relative speed between the target object and the detection radar (102); determining matched focusing parameters according to the parameters of relative motion, the focusing parameters being associated with the relative speed (103); and according to the received SAR detection signal, performing image focusing according to the focusing parameters when performing the SAR imaging, so as to obtain a focused SAR image (104). The present invention also relates to an SAR imaging system and a storage medium.
