Modeling of Airborne Ultrashort Wave Radio Receiver and Analysis of Lightning Interference Effect

Ultrashort wave radio receiver is an important part of airborne communication equipment, which may be affected by lightning during flight. Therefore, it’s necessary to analyze the electromagnetic characteristics and its performance under lightning interference of radio receiver. In this paper, we build the behavior model of ultrashort wave radio receiver system, then we analyze both electromagnetic characteristics in normal working condition and performance degradation under lightning interference. Through results we find that the sensitivity of the receiver deteriorates rapidly and the performance deteriorates seriously in the lightning environment. This work can provide ideas for the analysis of ultrashort wave radio and the design of lightning protection.
