Research on Electromagnetic Scattering of Leafless Trees and Targets Based on High Frequency Scattering Algorithm

The shooting and bouncing rays (SBR) method is widely used in the calculation of composite electromagnetic (EM) scattering between electrically a large target and backgrounds. This paper focuses on the scene of leafless trees and a typical target in late winter. The SBR is used to calculate the composite scattering radar cross sections (RCS) of the target and the leafless trees. This paper establishes the composite EM scattering model of leafless multi-tree and target, and studies the influence of leafless trees on the target. The simulation results show that two leafless trees with a height of about 7m cannot make a good shielding effect on the target.
