A new and robust constant false alarm rate (CFAR) detector based on truncated statistics (TSs) is proposed for ship detection in single-look intensity and multilook intensity synthetic aperture radar data.The approach is aimed at high-target-density situations such as busy shipping lines and crowded harbors, where the background statistics are estimated potentially contaminated sea clutter samples.-A new and robust constant false alarm rate (CFAR) detector based on truncated statistics (TSs) is proposed for ship detection in single-look intensity and multilook intensity synthetic aperture radar data.The approach is aimed at high-target-density situations such as busy shipping lines and crowded harbors, where the background statistics are estimated　potentially contaminated sea clutter samples.
