Abstract: The raw echo generation model is established considering the varying target electromagnetic scattering characteristics, and the module effects on azimuth and range direction are also presented. The echo generation and imaging results for typical target demonstrate the effectiveness of the proposed analysis method. Further improvement direction is put forward for the high resolution spaceborne SAR image simulation.

Key words: radar engineering, spaceborne synthetic aperture radar, high resolution, simulation error, electromagnetic scattering characteristic
