摘　　要：SAR卫星图像的分辨率直接影响着舰船目标识别结果。采用高分辨率SAR遥感图像,选取了两个较为直观的几何特征即长度和轮廓形状,对当前SAR图像舰船目标识别的能力进行了分析;给出了不同分辨率下的SAR图像的目标几何结构量算能力比对结果,为高分辨率SAR图像的舰船目标类型、识别算法研究提供相应支持。The resolution of SAR satellite image directly affects the result of ship target recognition.In this paper,high-resolution SAR remote sensing image is used to select two more intuitive geometric features,namely length and contour shape,to analyze the current SAR image ship target recognition ability.The comparison results of target geometry measurement ability of different high-resolution SAR images are given,which provides corresponding support for the research of ship target type and recognition algorithm in high-resolution SAR images.
