摘要
当入射波照射目标时,在某些角度范围内目标各部件之间常常存在耦合关系,导致新的强耦合散射中心产生。文章针对面-面耦合散射中心,从电磁散射机理出发,推导其后向散射电场公式,从而获得了耦合散射中心的频率依赖关系。
For the target illuminated by the incident wave,within some angle range,there is usually the coupling relationship between target components to produce a new strong coupling scattering center.Aiming at specular coupling scattering centers,the formula of backscattering electric field is derived from the physical mechanism of electromagnetic scattering,and the relationship of frequency dependence of coupling scattering centers is acquired.
