摘要 合成孔径雷达(synthetic aperture radar,简称SAR)通过对地面目标的多次照射来提高方位向上的目标分辨能力,由此使现有的SAR目标检测算法通常是一个基于SAR图像的后处理过程.在分析各种成像算法和现有的一些典型SAR目标检测算法的基础上,提出了一种在非成像状态下进行海岸线提取的新方法,把成像处理与目标检测问题有机地结合起来.通过真实星载SAR回波数据应用实验,证明了直接利用SAR回波对海岸线检测的有效性. As a kind of imaging radars, synthetic aperture radar (SAR) improves its resolution by means of moving and emitting pulse repetitiously. The issues about target detection of SAR are often a 憄ost-process?of the SAR imaging. A method for coastline extraction in the state of non-imaging based on analyzing the typical algorithms of SAR imaging and target detection is presented in this paper. Experimental results indicate the validity of the algorithm for coastline extraction. The algorithms are simple, able to recurrent, and easy for real-time processing and hardware implementation.
