Abstract :
Under millimeter-wave (MMW) High Squint Azimuth Scan SAR mode, this paper analyzes the influence of range migration. And SPECAN algorithm for this mode is presented. The correlation function, changed wavelength function and phase gradient autofocus for Doppler parameter estimation are analyzed. The imaging results for simulation and experiment verify the performance of these algorithms.
