| Summary: | The electromagnetic scattering of an ultra-high-speed plasma covered target is simulated by the field discrete Monte Carlo method. The flow field network is used to simulate the trajectory of electromagnetic wave particles according to the electromagnetic distribution parameters, and the electromagnetic characteristics are calculated according to the statistical parameters of the reflected particles. The computational time-consumption is less correlated with the incident electromagnetic wave frequency [except for the Radar Cross Section (RCS) valley characteristics], and it is convenient for parallel calculation, which realizes the fast calculation of the electromagnetic scattering of the electrically large plasma-covered target. On this basis, the electromagnetic scattering characteristics of the blunt cone hypervelocity target are calculated, and the main RCS reduction and enhancement mechanisms are given.
