The precondition of the knowledge that the intensity of radar cross-polarization scattering is weaker than the co-polarization is easy-to-be ignored. The precondition is that the target is symmetry on the plane established by the antenna and the target. The particular position makes the cross-polarization component of the target scattering significantly weaker than the co-polarization scattering component. In this paper, through theoretical analysis and experimental measurements, it is proved that the cross-polarized component is not weaker than the co-polarized in a broad sense. This conclusion is helpful to further develop the polarization measurement ability and improve the working performance of radar.%对于雷达目标交叉极化散射弱于共极化散射的认识,具有易被忽视的前提,即通常当目标关于由天线和目标所确立的平面对称时,因两者之间相对位置的特殊性才使得目标散射的交叉极化分量明显弱于共极化分量.通过理论推导和测量实验,对目标交叉极化散射强度进行了分析,并在相当广泛的意义上证明了交叉极化散射并不一定弱于共极化散射.该结论对于进一步挖掘雷达极化信息获取能力,进而充分利用极化信息提高雷达工作性能具有一定的启发意义.
