Effect on SAR Calibration from Transponder Time-Delay
有源转发器延时对SAR定标测量的影响

The effect of transponder time-delay on amplitude and phase of both range-compressed and azimuth-compressed signal are researched. Through simulation, the impact of transponder time-delay on imaging location, main-lobe, side-lobe of point target pulse response are analyzed and discussed under different resolution, different length of time-delay. Besides, the factors which need to be taken into consideration during time-delay setting are presented.
