摘　　要：雷达目标极化特性测量是雷达界关注的基本问题,在雷达目标极化增强和雷达目标极化识别等领域都具有重要应用。现有极化测量雷达普遍采用的分时极化测量方法受制于目标运动带来的影响,限制了其在上述领域的应用。文中以目标散射功率矩阵为测量对象,通过设计极化处理方式,克服了目标运动带来的影响,分析和验证了测量误差的统计特性和测量性能。The measurement of radar target polarization characteristics is always of concern in the radar community. It has important applications to the fields of polarimetric contrast enhancement and polarimetric recognition. However, the universally adopted interleaved-pulse polarization measurement method is limited by the effect of target movtion. The scattering power matrix of target is taken as the measurement item in this paper. The effect of target movtion is overcome by proper design of the polarization processing method. Statistical characteristics of measurement error and measured performance are analyzed.
