摘　　要：为了分析蒸发波导下海杂波对雷达探测的影响,以K-分布模型作为研究对象,采用基于球不变随机过程(SIRP)法对其进行仿真;通过分析仿真结果确定了K-分布海杂波形状参数、蒸发波导高度和雷达探测距离之间的关系。结果表明,蒸发波导高度越高,海杂波降低雷达的探测性能越明显。相关结果可以为新型雷达系统的设计及实际应用起到指导性作用。In order to analyze the influence of sea clutter on radar detection in evaporation duct,the method of spherically invariant random process was proposed to simulate K-distributed sea clutter in evaporation duct. The simulation result shows the relations among the K-distributed sea clutter shape parameter,the evaporation duct height and the detecting range. The result shows higher evaporation duct makes sea clutter influence more on radar detection. The results provide guidance for design of new radar system and practical application.
