Retrieval of subsurface soil moisture using SAR observation at UHF/VHF bands[J]. Journal of Remote Sensing, 2009,13(1):24-29. DOI: 10.11834/jrs.20090102.
A three-layer scatter model is developed for the retrieval of moisture profile of the terrain subsurface under SAR observation at UHF/VHF bands.Based on different penetration depths at UHF and VHF channels
scattering observations at these two bands are alternatively used to iterate the retrieved moisture of the layered media
and finally reach the convergence of the moisture profile of the layered subsurface media.
