摘　　要：本文推导了相关广义伽玛分布随机变量为球不变随机变量的条件;并在此基础上利用SIRP(球不变随机过程)法模拟仿真了相关广义伽玛分布序列;并给出了基于SIRP法的相关广义伽玛分布序列仿真的原理和方法流程图,利用此方法产生了三种常见分布(瑞利分布、韦布尔分布、伽玛分布)序列,证实了此方法的通用性。最后分析了实测宽带雷达树林杂波数据,证明了此方法的实用性。This paper derives the condition which the correlated generalized gamma （GΓ） random vectors are SIRV （ Sphere Invariability Random vector）. According to this condition ,the correlated GΓ distribution sequences are simulated by SIRP （Sphere Invaria- bility Random process）. The method using SIRP to generate correlated GF random sequences and its flow chart is presented, and the uni- versality of the method is proved by generating three kinds of conditional distribution （ Rayleigh distribution, Weibull distribution, Gamma distribution） sequences. Finally, the practicability of the method is proved by analysis of the real Wide Band radar Hurst clutter.
