极化雷达测量体制研究进展

Development Study of Polarimetric Radar System

文中从极化雷达发展趋势的角度,对极化测量关键技术进行了梳理,明确了极化测量雷达体制的概念和内涵,并通过暗室测量实验和仿真实验比较了各测量体制间的差异和优缺点,证明了在目标极化特性快起伏情况下,分时极化测量不能完整准确地反映目标极化特性,此时瞬时极化测量的性能明显优于分时极化测量,并指出了紧凑极化体制的特点及应用。

In this paper, from the point of view of polarization radar and its development trends, the key technologies ot polarization measurements are studied, a clear concept and content of polarimetric radar system is given and then comparison between measure- ment systems is made in the difference, advantages and disadvantages through darkroom experiment and simulation. It is proved that the time-sharing polarimetric cannot complete and reflect target polarization scattering property. Instantaneous polarimetric per- formance is better than time-sharing polarization system. The characteristic and applicaiton of compact polarization system is pointed out.
