具有任意电特性的平面对称目标的圆极化双基地散射具有反射不对称性、极化反转不对称性和极化反转反射对称性，这些对双基地雷达数据解释是有用的。熟悉这些双基地散射极化特性也将有助于解释偏置反射器天线特性中的去极化和波束位移现象。此外，对称性可用于减少从双基地散射距离测量、偏置反射器天线测量以及理论或计算机计算获得数据的时间和费用。导出了反射不对称性、极化反转不对称性和极化反转反射对称性关系。然后将对称关系与电磁互易原理相结合，以确定表征目标散射所需的最小测量次数。
Circularly polarized bistatic scattering from plane-symmetric targets with otherwise arbitrary electrical properties exhibits reflection asymmetries, polarization reversal asymmetries, and polarization reversal reflection symmetries which are useful for bistatic radar data interpretation. Familiarity with these bistatic scattering polarization properties will also facilitate the interpretation of depolarization and beam displacement phenomena in off-set reflector antenna characteristics. In addition, the symmetries can he used to reduce the time and expense in obtaining data from bistatic scattering range measurements, offset reflector antenna measurements, and theoretical or computer calculations. The reflection asymmetry, polarization reversal asymmetry, and polarization reversal reflection symmetry relations are derived. The symmetry relations are then combined with the principle of electromagnetic reciprocity to determine the minimum number of measurements needed to characterize target scattering.
