Abstract

Abstract: Aiming at the issue of distribution regularity of field strength in vehicle cab under excitation of vehicle-borne high-power VHF antenna, a method of numerical simulation combining with extreme value theory to predict maximum field strength is proposed, which minimizes sample collecting difficulty and fitting deviation. CST simulation software is applied to get field strength sample in vehicle cab, and generalized extreme value (GEV) is used to fitting entire field strength distribution. peak over threshold (POT) model based on Generalized Pareto distribution is used to research high field strength value sample statistical characteristics. Resultsshow that under antenna excitation of 92.5 MHz working frequency at different installation positions the field strength in vehicle cab all follows GEV distribution, and the deviation is lower when using GP distribution fits high value of strength field; at a certain quantile the maximum value of field strength in vehicle cab is calculated by using POT model.
