摘　　要：在SAR目标边缘提取的基础上,为了获取目标边缘详细信息并对目标准确定位,该文针对线性目标设计了目标重心提取算法,对环状目标设计了轮廓线追踪算法,并给出了对目标范围、中心点标识、目标横向、纵向“直径”等的计算方法。这些算法在不同图像上取得了良好的检测结果。A new algorithm for automatical extraction of target information in post-processing SAR image is presented.Extraction barycentric coordinate is designed for linear objective.For cyclic structure targets,robot snake model is used to track contour at those pixels where contour pixels are consistent.Methods based on global search techniques can acquire available information such as target width,target height and target center coordinate and so on.The computation procedure is given and results are analyzed for various images.Experimental results demonstrate the attained quality.
