摘　　要：基于海杂波与噪声分界是对海搜索雷达探测海面小目标的一项关键技术,首先分析了高分辨雷达的海杂波与噪声的分布关系,然后提出了通过在距离维进行开窗,利用滑窗统计方差来搜索海杂波与噪声分界点的方法,最后通过实测数据分析,验证了分界算法的可行性,分析结果对工程应用具有一定的参考意义。The division analysis between sea clutter and noise is one key technique upon small target detection for maritime radar. In this paper, the distribution relationship between sea clutter and noise of the high resolution is firstly analyzed. Then, a method of the division between sea clutter and noise using variance statistics of sliding window in the range direction to search the division spot is proposed. In the end, the feasibility of the division algorithm is proved by simulation, and the result of analysis makes some sense to the engineering application.
