Abstract :
A reformative SAR bandwidth synthesizing method to produce high range resolution through stepped frequency chirp signal is introduced in this paper firstly. Then according to the requirement of engineering application, the effect of system error which is inherent in radar system on synthetic results is analyzed. And a compensation algorithm based on range PGA in frequency domain is presented. At last simulation results validate the algorithm.
