%X The SAR imaging of moving ship targets at sea is investigated based on high resolution airborne SAR with longer synthetic aperture time. Because the scatterers at different range cells may have different Doppler characteristics, the range migration correction for moving ship is completed by coarse and fine correction procedures. The compensations of second and higher order phase terms are implemented in "range frequency - azimuth time" domain. A new time-frequency analysis imaging method is presented for higher image resolution by means of the combination of Short Time Fourier Transform (STFT) and Complex Dual Apodization (CDA). The imaging results of real SAR data show the effectiveness of this method.
