摘　　要：针对零记忆非线性变换(ZMNL)法无法模拟非对称形状功率谱的问题,在解决形状参数取值受限问题的基础上,对Pareto杂波功率谱仿真方法进行改进,实现了非对称杂波功率谱的仿真。实验表明,只要形状参数选择恰当值,其频谱泄漏水平在要求的范围内,就能够生成形状参数为非整数、功率谱为非对称形状的Pareto分布杂波。There is a problem that power spectrum shape is limited in the method of ZMNL.On the basis of solving the problem of shape parameters,this paper improves existing methods of power spectrum simulation and simulates the power spectrum of asymmetric shape.The simulation results show that the clutter simulation of Pareto distribution can be generated,which contains non-integral shape parameters and power spectrum of asymmetric shape,when the shape parameter values are properly selected and the spectral leakage is acceptable.
