摘要
海杂波作为一种具有统计特性的随机变量,它的特性可以用幅度分布特性和谱特性来描述,这里提出了基于K分布的高精度雷达海杂波模型和仿真算法。零记忆非线性变换法ZMNL(zeromemory nonlinearity)可以产生相关和非相关的雷达杂波。对高精度雷达产生的海杂波利用K分布进行了仿真,对这种算法的思路和实现步骤进行了说明,并利用ZMNL方法产生符合该分布的海杂波,同时详细地给出了杂波产生的方法及过程。
Sea clutter is described as random processes statistical characterization of the clutter requires marginal probability density functions of its samples.The paper proposes a sea clutter model and a simulation method based on K-distribution for high-precision radar.Zero memory nonlinearity can generate coherent correlation radar clutter.The paper simulated the radar sea clutter in high-precision radar by K-distribution and presented the sea clutter according with K-distribution following ZMNL.The method to produce the clutter was detailed.The clutter used the method had a good match with real sea clutter signal.It has a important meaning to the radar-electronic-war simulation and the design of radar detector.
