摘　　要：准确而有效地模拟雷达杂波信号,对于雷达系统设计和雷达信号处理具有重要的意义。文中提出了一种基于SIRP(球不变随机过程法)的相关学生t分布雷达杂波模型和仿真算法。对这种算法的思路和实现步骤进行了说明,并给出了实现模型和仿真结果。计算机仿真的结果证明,利用学生t分布来描述相关雷达杂波的"长拖尾"是合理的;利用学生t分布来描述相关雷达杂波必须使得形状参数的取值大于1。Accurately and effectively modeling radar clutter signal plays an important role in radar design and radar signal processing. In this paper, the correlation student t-distribution radar clutter model and simulation algorithm based on spherically invariant random processes（SIRP） are presented. The scheme and implementation procedure of this algorithm are illustrated, and the implementation model and simulation results are given. The computer simulation results can prove that it is reasonable to use student t distribution to describe the long hangover of correlation radar clutter. Using student t-distribution to describe correlation radar clutter, the valuation of the form parameter of student t-distribution must be greater than one.
