角反射器阵列排布设计及其散射特性研究
Design of corner reflector array arrangement and study of its scattering characteristics
摘要
Abstract
The corner reflector as a passive jamming device for anti-radar detection has strong radar echo characteristics.Arranging the corner reflector array according to the scattering center model of an important target can better simulate the radar characteristics of the target to achieve jamming,which has important military application prospects.In order to reasonably arrange the corner reflector arrays to simulate the electromagnetic scattering characteristics of the important targets in the actual scene,this paper constructs a complex electromagnetic scattering model of the target in the complex scene based on the fast imaging technology of the bounce ray method,and proposes an optimal arrangement method of the corner reflector arrays based on the scattering center model of the target attributes.Simulation experiments analyze the electromagnetic scattering characteristics of different types of corner reflectors under different radar incidence angles.At the same time,combined with different interference effect evaluation indexes,the simulation experiment verifies that the target interference effect of the corner reflector array designed in this paper is more than 85%under multiple radar incidence angles,and the corner reflector array has the ability to protect important targets as passive interference.关键词
