摘　　要：研究了远程预警雷达海杂波的建模、仿真及实现问题。结合远程预警雷达在应用中距离分辨率和入射余角的实际特点,建立了海杂波幅度分布和功率谱的模型。其幅度分布采用相干相关K分布模型,功率谱采用高斯模型。信号产生方法采用球不变随机过程法。仿真结果证明了模型和算法的有效性。The model and simulation of the sea clutter of long-distance early-warning radar is introduced. According to the actual characters of range resolution and grazing angle ,the models of sea clutter＇ s amplitude distribution and power spectrum are modified. The coherent related K -distribution model is used in amplitude distribution. The Gaussian model is used in power spectrum. The applicability and effectiveness of the model and the simulation method is proved with the results of simulation.
