| 摘 要： | 应用零记忆非线性变换法(ZMNL),对幅度分布特性为瑞利分布、对数正态分布和韦伯分布,功率谱特性为高斯谱和平方谱的地杂波进行建模和仿真.实现了实时动态地模拟实际采集的雷达地杂波,而且可按给定的功率谱模型产生满足非高斯分布的随机数据序列.仿真结果和理想模型的吻合,证明了ZMNL是有效的地杂波仿真方法.最后研究了ZMNL方法产生误差的原因,以及ZMNL方法的适用范围.

| Abstract: | The ground clutter models and simulation algorithms available at present are summarized. The correlated vectors for ground clutter are considered for Rayleigh, Log-normal and Weibull distributions. Using typical models, ground clutters are generated on computer for the study of the feasibility of ZMNL algorithms. Simulated results show the validity of this algorithm. |
