| 摘 要： | 根据电磁场叠加原理,给出了一种与观测天线无关的广义雷达散射截面(RCS)定义,引入对称极化等多种极化散射特征量,计算了近距离观测时金属平板目标的极化RCS曲线;根据广义RCS的定义,在近场电磁散射建模中分解照射场和合成接收,提出了一种有效的近场电磁散射建模方法,并比较了采用方向图等效近似和场分解合成两种方法计算的金属平...

| Abstract: | A definition of generalized radar scatter section(RCS) which was independent of antenna was presented based on the superposition principle of electromagnetic field in this paper.Besides the vertical and horizontal polarization,the symmetric polarization was supposed to be a third near-field polarization scattering characteristic,and more near-field polarized RCS of metal slab were calculated.According to the generalized RCS definition,a more efficient method that was decompose-compose method was given out,f... |
