Synthetic Aperture Imaging Ladar Imaging Algorithm
合成孔径成像激光雷达成像算法研究

FMCW signal and its characteristic in balanced heterodyne detecting were described.The difference in instantaneous slant range between SAIL and conventional SAR were analyzed.A Doppler shift term was induced by the continuous motion of the platform that was ignored by conventional SAR in "stop-and-go" model.A refined frequency scaling algorithm was deduced,which was suitable for airborne SAIL in stripmap model and was taking the Doppler shift term into account.The simulation result shows that the given algo...
