Aperture-dependent motion compensation is important for wide beam Synthetic Aperture Radar （SAR） data processing. This paper studies a wide beam motion compensation algorithm based on frequency division. It takes blocks along azimuth dimension in frequency domain and applies angle-variant motion com...
