| titleOfInvention | Soil humidity estimation method and device for vegetation coverage area |
| abstract | The invention discloses a soil humidity estimation method and a soil humidity estimation device for a vegetation coverage area, which belong to the fields of electronics, information, optical remote sensing and the like, and firstly, a relation between an overall backward reflection coefficient and DDM (distributed data model) reflection power is constructed by means of satellite-borne GNSS-R reflectometer data; solving vegetation reflection coefficients and attenuation coefficients of the vegetation coverage area by using the optical image data; the method comprises the steps of fusing the relation between the total retroreflection coefficient and the DDM reflected power of satellite-borne GNSS-R reflectometer data and vegetation information in optical data, and solving the relation between the pure soil surface reflection coefficient and the DDM reflected power of a vegetation coverage area; establishing a soil humidity and DDM reflected power regression model by using measured data of soil humidity of a plurality of control points; and substituting the DDM reflected power of certain point GNSS-R data into a regression equation to invert the soil humidity. The implementation of the method is effective fusion of the data of the satellite-borne GNSS-R reflectometer and the multispectral remote sensing data image together for inverting the soil humidity of the vegetation coverage area. |
