某车载雷达的防雷研究

摘要

The vehicle radar is easy to get lightning strike when it works on dry and wide highland .The meth-od 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 resist-ance of lightning rod on dry land .The lightning proof of vehicle radar in dry land is improved effectively .%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。
