摘　　要：提出了一种基于天波超视距雷达地、海杂波频谱特性,采用空间单元杂波幅度峰值检测结果判别地、海及地海交界线杂波属性的方法,可判别出具有多普勒频率偏移的地海杂波,并利用某雷达实测数据对该方法进行了验证。采用该方法绘制出的某区域海岸线地海杂波分布图与地图形状基本吻合。Based on the spectrum characteristics of skywave over-the-horizon radar（ OTHR） clutter, the method of using the amplitudepeak detection results of space units to discriminate the attribute of OTHR clutter is presented. The method improved attributediscrimination rate of OTHR clutter with Doppler offset. By analyzing the radar measured data, the feasibility and correctness ofthis method is proved. The outline of shoreline clutter map drawn by this method accords with real map.
