| Abstract: | A scheme for modification of the polarorbiting satellite image receiving set WT-lA was carried out successively in the period of 1984-1985. The laboratory works included: improving the capability of the antenna element in receiving both the linear and the circular polarized sat. signals, lowering the noise temperature and improving the frequency stability of the whole set, spreading the threshold level of the demodulator, etc.
From the field tests in the period of 1985-1986, high quality cloud images have been got from both the GMS-3 and NOAA series weather satellites, and all the technical specifications of the modification scheme have been satisfied. |
