The Application of Sea Wave Slope Distribution Empirical Dependences in Estimation of Interaction Between Microwave Radiation and Rough Sea Surface

摘要

The use of hydrological (surface wind and sea wave slope) dependences for the calculation of microwave characteristics of the “ocean–atmosphere” system by Kirchhoff method is discussed here. As an important example, we review results of our experiment on bistatic sensing of the sea surface. In this experiment, Sun is a powerful natural source of noise microwave radiation for the sea surface sensing. For the receiving of solar radiation in the region of quasi-specular scattering, three two-polarization radiometers (0.8, 2.25, and 6.0 cm) are used. The results of joint hydrological and radiometric experiments (wind speed from 0 to 15 m/s) are reported. As a result, the improved quantitative model for microwave (3–50-GHz band) radiometric calculations in remote sensing of “ocean–atmosphere” system is presented.
