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.

Key words: ground clutter, clutter modeling, ZMNL algorithm
