摘　　要：针对车载雷达在高地势开阔、干燥地区容易受到雷击威胁的情况,分别介绍了直击雷和感应雷的车载雷达防雷措施,并通过MATLAB进行了单根避雷针保护范围的三维分析;采用更换土壤、深埋电极、添加降阻剂等多种措施降低干燥地区避雷针的接地电阻,有效地提高了干燥地区车载雷达的防雷效果。The vehicle radar is easy to get lightning strike when it works on dry and wide highland. The method of protection against direct lightning strike and indirect lightning strike is introduced. The three-dimensional model of the protection range of single lightning rod is obtained via MATLAB programming. Changing soil, embedding electrode deeply, adding resistance-reducing agents are introduced for reducing grounding resistance of lightning rod on dry land. The lightning proof of vehicle radar in dry land is improved effectively.
