| 摘 要： | 海杂波仿真对测试雷达在杂波环境下的检测性能是极其重要的.K分布可以很好地描述高分辨低入射余角雷达的杂波特性.使用球不变随机过程法模拟产生相干相关K分布的海杂波,该方法允许对杂波的协方差阵和分布函数分别独立进行控制,从而克服了传统零记忆非线性方法产生相干相关K分布杂波的困难.仿真结果证明了该方法的有效性.

| Abstract: | The simulation of sea clutter is important for testing the radar performance in the clutter environment.The characteristic of sea clutter can be described by K-distribution model.The simulation method based on Spherically Invariant Random Process(SIRP)is presented.The SIRP allows independent control of the covariance matrix and probability density distribution function,which overcomes the difficulty of conventional Zero Memory Non-Linear method in producing the clutter.The result of simulation shows the eff... |
