杂波能显著降低雷达探测目标的能力。利用零均值非线性变换(ZMNL)方法可由零均值高斯白噪声得到满足所需概率密度函数的杂波序列。而要使杂波序列满足特定功率谱分布,可利用零均值非线性变换前后的自相关系数设计线性滤波器。数值仿真结果验证了线性滤波器与ZMNL结合产生满足特定概率密度函数和功率谱相关杂波序列的有效性。
Correlated Clutter Can significantly reduce the radar performance.Using zero-mean nonlinear transformation(ZMNL) method,the clutter sequence with a certain probability density function can be generated by zero-mean Gaussian white noise.For the clutter with a certain power spectrum distribution,the linear filter need be designed by correlation coefficient of ZMNL.Numerical results show the combination of the linear filter and ZMNL can generate the clutter sequence with probability density function and power spectrum.
