| 摘 要： | 介绍了一种用零记忆非线性变换(ZMNL)模拟具高斯谱特性的相参相关Weibull分布海杂波的方法。由正交白高斯噪声序列经线性滤波器产生相关的正交高斯序列,用ZMNL将该序列通过非线性变换为相参相关Weibull杂波。仿真结果表明,该法形成的海杂波信号与理论值吻合较好,方法可行。

| Abstract: | A method of imitating interference correlated Weibull distribution sea clutter with Gaussion spectrum by using zero memory none linearity(ZMNL) transform was put forward in this paper.The correlated orthogonal Gaussion sequence was produced from orthogonal white Gaussion noise sequence through linear filter.Then the correlated orthogonal Gaussion sequence was transferred to the interference correlated Weibull clutter through none linear transform by using ZMNL.The simulation showed that the sea clutter acquired by this method was agreed with the theoretic one.The method was feasible. |
