摘　　要：极化信息的获取和利用对提高雷达目标的检测、分类识别和抗干扰性能具有重要作用,在气象观测、对地遥感侦察和防空反导等领域得到了高度重视和广泛应用。极化测量是极化信息获取和处理的基础,在雷达极化技术发展过程中出现了多种测量体制。从极化雷达的发展历程和趋势的角度,对极化测量体制进行了梳理,阐述了典型极化测量雷达体制的概念和内涵,比较分析了各测量体制间的差异和优缺点,并指出了其主要应用领域,这为极化雷达体制选择与优化设计提供有益参考。Acquiring and utilizing polarization information is of great importance for improving radar detec- tion, anti-interference and classification ability. It receives generalized attention and has broad application pros- pect in the area of weather observation, remote sensing and air defense. The polarization measurement is the foundation for polarization information acquiring and processing, and there are several polarization measurement modes in the radar polarization development history. From the respect of history and development tendency, the mathematical principle of polarimetric is given, and the connotative definition of polarization radar mode is presented. The differences and disadvantages of these modes are compared and analyzed. The application do- mains of different polarimetric radar are pointed out. It is useful for the choice and optimization of polarimetric systems.
