Abstract
We present a theoretical analysis for InSAR height measurement in sand-covered arid areas based on two-layer model. The influence of radar wave's penetration on height estimation is mainly considered. If the returned signal from the subsurface is dominant, InSAR is potential to measure the subsurface height. Taking the refraction at the interface and the change of propagation velocity in the sand layer into account, a modified InSAR method is proposed in this paper. Simulations are performed to validate the proposed subsurface InSAR method.
