本文在双基地极化测量的框架内，讨论了双基地几何结构和目标特性对极化测量的纠缠效应。三种不同的几何效应的区别：天线旋转，目标定位，和双基地角。天线旋转是通过使用极化基地作为参考平面的散射平面。由于只研究球体，因此不考虑目标方向效应。本文通过对经典参数的双站极化分析，重点研究了双站角度效应。研究了在共振区由单个或多个球体组成的靶。最后，室内极化测量的结果，这样的目标，并进行了讨论。
Within the frame of bistatic polarimetry, this paper discusses the entangled effects of bistatic geometry and target features on polarimetric measurements. Three different geometrical effects are distinguished: antenna rotations, target orientation, and bistatic angle. Antenna rotations are addressed through the use of polarimetric bases taking the scattering plane as the reference plane. Target orientation effects are not considered since only spheres are studied. This paper focuses on the bistatic angle effect through a bistatic polarimetric analysis on classical parameters. Targets consisting of single or multiple spheres in the resonance region are investigated. Finally, the results of indoor polarimetric measurements on such targets are presented and discussed.
