Fast Scattering Compuation of Group Targets Based on Current Iteration

this paper proposes a fast method to compute the scattering field of group targets through current iteration. The initial induced currents of the target are computed by full wave numerical method. To validate the feasibility of this method, the scattering field of unmanned aerial vehicle (UAV) swarm targets computed by this method are compared with the results of full wave numerical method. The comparison results show good agreement between the two results, and the calculation time and memory consumption of this method are obviously lower than the full wave numerical method.
