摘要
复合K分布统计模型能够很好的描述海杂波的幅值与相关性特征。通过建立海杂波幅度分布特征、时间相关性与空间相关性模型,利用球不变随机过程(SIRP)方法可以仿真时空相关K分布海杂波序列。在舰载导航搜索雷达系统模拟中应用该方法来模拟生成海杂波,能够逼真地表现海杂波随雷达环境的变化。仿真结果表明了该方法的有效性。
Compound K-distribution model can illustrate the sea clutter＇s amplitude distribution and correlation properties. By modeling the sea clutter＇s amplitude distribution, temporal and spatial correlation, we can use SIRP to simulate the sea clutter sequence with K distribution and temporal and spatial correlation properties. The appliance of it in the simulation of shipborne radar, the simulation of radar＇s high resolution display system is one of the most important procedures in radar simulation can realistically depict the sea clutter which vary with the radar environment. The result proved that the arithmetic is right.
