| Abstract: | 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. |
