We analyze detailedly the azimuth preprocess principle and propose the band-pass filtering sub-aperture method, which can simplify the process effectively.
The focused synthetic aperture imaging processing is the available method to improve the azimuth resolution, but the operational quantity is so large that it could not accomplish in real time.
