雷达通信杂波序列的模拟

Simulation of Clutter Sequence for Radar

分析和讨论了基于几种不同的分布而产生不同雷达通信杂波的序列,使用不同方法进行仿真,将所得的结果与理论值进行了对比。通过对不同方法(协方差矩阵三角法、反变换法、ZMNL-零记忆非线性变换法)所得的仿真和理论对比可知,这3种方法都能较为有效地对特定幅度统计特性的雷达杂波进行仿真,尤其是ZMNL方法,幅度概率分布以及功率谱的仿真结果都与理论值吻合较好,并且运算速度快,是一种有效的雷达杂波仿真方法。

Several kinds of radar-communications clutter sequences based on different distributions are analyzed and discussed in this paper.Then the simulations with the facts by different methods,namely Covariance-Matrix-Triangle,Inverse-transform and Zero-Memory-Nonlinear,are compared.By comparison,we know that all these three methods can satisfy the amplitude probability distribution effectively.Especially,when we apply the ZMNL,both the amplitude probability distribution and power spectra can quite well accord with the fact with its high computing speed.Simulations show the validity of this method.
