Finally, the soil moisture retrieval method proposed in this paper was evaluated by comparing with the soil moisture data provided by SMAP. The results show that the soil moisture retriev

The results show that the random forest algorithm used in frequency inversion is more effective than the amplitude an

Among them, the average RMSE of the ZTD models with RBF is 20.8 mm and 20.1 mm for two data-fusion strategies, respectively. The accuracy of

The first step is to unify the time and space systems, then make full use of the multi constellation carrier phase measurements, and finally e
