摘要
作为一种具有统计特性的随机变量,海杂波的特性可以用幅度分布特性和谱特性来描述。文章以韦伯分布、具有高斯谱的海杂波为例,介绍一种海杂波的模拟模型;之后进行海杂波信号仿真并验证了仿真结果。仿真得到的海杂波数据可以直接用于雷达目标模拟器中的输入信号。
Sea clutter is described as random processes. Statistical characterization of the clutter requires marginal probability density functions of its samples. In addition, the clutter may be highly correlated. In this paper, a method generating a random sequence with a specified pdf and auto-covariance is described. The modeling and simulating of sea clutter is showed. The generated signal can be used in the simulation of the Radar system.
