舰船检测是合成孔径雷达图像海洋应用的一个重要部分。本文设计了舰船检测步骤，给出了SAR图像舰船形状分析的方法，对于舰船目标进行自动检测并计算出舰船参数，通过实验验证目标的检测与分析是有效的。

The detection is one for the important ocean applications of Synthetic Aperture Radar (SAR) image of ship. The ship detection processing steps are presented and ship shape analysis method is suggested. The ship targets are automatically detected and the parameters of ship are calculated. Experimental results show that the method is efficient.
