摘　　要：提出一种新型的W波段数字变极化目标特性测量雷达.该雷达由两子阵变极化天馈、两通道TR模块与数字处理单元构成,采用空间波束合成任意极化发射、数字方式实现任意极化接收.通过目标实验结果表明,该雷达能在多种极化体制下准确提取目标极化散射矩阵,具备测量目标全极化RCS能力以及可用于目标极化特性分析与研究.A novel W-band digital variable polarimetric radar for target characteristic measurement is presented in this paper. The main components of the digital variable polarimetric radar are the two-subarrays variable polarized antenna, the two-channels T/R modules, and the digital signal processing unit. This radar transmits arbitrary polar- ized electromagnetic wave by spatial polarimetric synthesis, and receives arbitrary polarized echo by digital polari- metric synthesis. The experimental results illustrate that the W-band digital variable polarized measurement radar can extract the polarimetric scattering matrix accurately under various polarimetric modes, has the ability of measur- ing full-pol RCS of the target and can be used for target polarimetric information analyzing and research.
