This paper proves that the Microwave Polarization Difference(PD) Index ( MPDI ) can be used to indicate the vegetation coverage conditions with the AMSR-E L2A brightness temperature data product. 以AMSR-E数据为例,研究证明了微波极化差(PD)异指数(MPDI)能够反映地表植被覆盖状况。
Denoting the polarization difference, a polarization index ( PI ) of microwave radiance from the terrain surface is derived from the radiative transfer model. 用辐射传输理论提出的地表微波辐射极化指数PI的定义,分别指出了土壤湿度、地面粗糙、植被层和大气层的各自影响。
The minimum polarization difference criterion is presented, based on which, the genetic algorithm ( GA ) optimization of electric performance of radome walls is studied. 提出最小极化差(PD)异准则并基于这一准则对实际的C-夹层雷达天线罩壁进行遗传算法(GA)优化研究。
