Rebuilding the sea wave height spectrum by using microwave scattering characteristics
Tóm tắt
The microwave back-scattering characteristics are numerically analysed by the electromagnetic scattering theory, and the sea wave height spectrum that reflects the wind field is rebuilt by comparing the calculated data with experimental data which were measured by airborne scatter. According to the wave height spectrum, the relationship between the back-scattering coefficients and wind speeds can be obtained. Once the back-scattering coefficients of the sea surface are measured, then the wind speeds over the sea surface can approximately be determined. It is useful for the microwave remote sensing in ocean.
