Ground point selection method based on vehicle ground current distribution regularities

The invention relates to a ground point selection method based on vehicle ground current distribution regularities, and belongs to a vehicle ground point selection method. The ground point selection method comprises the steps of establishing a vehicle electromagnetic simulation model by using CST (Computer Simulation Technology) MS electromagnetic simulation software through setting a polarization angle, an incident angle and an incident direction; carrying out simulation calculation on vehicle ground current distribution by using the CST MS software; changing simulation conditions, and simulating vehicle ground current distribution under each condition one by one; and determining the vehicle ground current distribution regulations, and based on the regulations, guiding selection of a position of a vehicle ground point. The ground point selection method has the advantages that by simulating the attack of a real high altitude nuclear explosion electromagnetic pulse to a vehicle, a relationship between the freq
