| 摘 要： | In this paper, the principle and method of microwave remote sensing atmospheric sounding are described. In order to carry out the experimental study, the 4 channels in 5mm—1.35 cm band microwave radiometers have been constructed. The field experiment in September-October 1981 was carried out. In this paper, the results obtained by different inversion methods are compared with each other. The experimental result shows that it will be satisfactory, if the temperature profile and inversion of lower atmosphere are derived from remote sensing of 2 channels (frequencies: 52.8 Gc and 54.4. Gc) in 5 mm band. The atmospheric humidity can be obtained from the remote sensing of 1.35 cm band. While the change of air mass exists, signal reveals itself significantly in the atmospheric microwave radiation. The variations of atmospheric temperature and humidity have been analysed and compared with those obtained from radiosonde.
