| 摘 要： | 机载脉冲多普勒雷达在高重频模式下的海杂波仿真精确度是影响整个雷达系统仿真的先决因素。在分析基于网格法的杂波功率谱模型的前提下,设计了一种利用杂波功率谱进行时域重构,产生幅度分布服从对数-正态分布海杂波的仿真模型。仿真结果与理论值吻合较好,说明仿真开发模式是可行的,仿真模型是正确、有效的。

| Abstract: | The accurate simulation of sea clutter of airborne pulse-doppler radar under high pulse repetition frequence is a prerequisite for the whole radar system.The mesh model of power spectrum is introduced and a method of generating log-normal distribution sea clutter by reconstruction in time domain using power spectrum is designed.The result of simulation validates the feasibility and accuracy of this method. |
