High-power Microwave Damage Assessment Method for UAV

Abstract

To evaluate the damage assessment of high-power microwaves on complex electronic systems, a damage assessment method combining top-down system analysis and bottom-up comprehensive evaluation is proposed. A UAV damage tree model was constructed, and the FAHP-CRITIC method was used to assign weights to system components. The pulse energy transfer and coupling process are analyzed, and a neural network system is introduced to predict the damage degree of the parts considering the influencing factors of the damage degree of the parts. Based on the obtained component weights and damage degree, the system damage degree is calculated by the constructed nonlinear discontinuity function which satisfies the serial structure of the electronic system. Then, the mapping of system damage degree to ruin level is realized through the affiliation function. Finally, simulation calculations are carried out for the UAV to verify the feasibility and effectiveness of the proposed method.
