| 摘 要： | 针对雷达海杂波相干视频散射模型,给出了一种通用的计算机仿真模型.提出用迭代算法和随机向量法完成无记忆非线性变换过程,产生非高斯相干随机序列.其中迭代算法用来计算非线性变换过程中高斯序列相关性的变化,而随机向量法用来完成线性变换, 仿真实验数据证明利用这种方法可精确地产生具有指定概率密度和功率谱的非高斯随机序列,逼真地复现既包含振幅又包含相位的雷达海杂波相干视频散射信号.同时给出了迭代算法使用过程中的注意问题及海杂波模型仿真的过程和结果.

| Abstract: | A general computer model is presented for simulating the coherent video echo scattering model of radar sea clutter.Iteration algorithm and random vectors method are proposed to fulfil the transforming process of zero-memory nonlinearities and to generate non-Gaussian coherent random sequence.The iteration algorithm is developed to calculate the variation of Gaussian sequence pertinence in the process of nonlinearities transformation,and the random vectors method is developed to implement the linearity trans... |
