| 英文摘要: | Polarimetric Microwave Imager (PMI) is planning as one of the main payload on WCOM satellite with the purposes of collecting the radiation from the Earth surface to retrieve the geophysical parameters of the land, ocean and atmosphere. PMI is passive microwave radiometer with frequencies of 6.8, 10.7, 18.7, 23.8, 37.0 and 89GHz. The radiometers at 10.7, 18.7 and 37.0 GHz are full-polarized to measure four Stokes of the surface, whether from the ocean or the land. The other frequencies are traditional radiometer with vertical and horizontal channels. Since the third and the fourth Stokes parameter are sensitive to the orientation feature of the surface, they can be used to retrieve the wind vector, rain, snow cover, forest distribution and polar icecaps. Furthermore, with the higher resolutions at 37.0 and 89.0 GHz, the freeze-thaw on the land and rain on the ocean can be more accurately evaluated. In the paper, some primacy consideration and design on PMI are given for the application fulfilling the requirements of WCOM. |
