Abstract

It is important to investigate the electromagnetic environmental effects of the UAV swarm under strong electromagnetic wave irradiation. It is also the basis for the design of UAV electromagnetic protection. In order to solve the problem of large calculation areas, many solution objects with fine structures in the simulation, the whole solution task is decomposed into three problems, including spatial propagation, front-door coupling and back-door coupling, to reduce the complexity of the solution. The calculation methods for UAV electromagnetic environmental data and the internal coupling effect are proposed. A simulation example is performed. The time domain and frequency domain of the interference coupling waveform are obtained. The magnitude of the interference field strength is analyzed. It provides a good reference for the evaluation of electromagnetic protection capability and protection design of micro-sized UAVs. The research finds that the simulation task decomposition method proposed in this paper can be used to transform the simulation of the electromagnetic environmental effect of UAV swarm into multiple relatively simple tasks. The difficulty and complexity of the solution is then significantly reduced.
