| Abstract: | Acquiring and utilizing polarization information is of great importance for improving radar detection, anti-interference and classification ability. It receives generalized attention and has broad application prospect 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 domains of different polarimetric radar are pointed out. It is useful for the choice and optimization of polarimetric systems. |
