Finally, a multi-frequency polarimetric inversion algorithm for the retrieval of subsurface soil properties using VHF/UHF band radar measurements is devised. The top soil dielectric constant is first determined using an L-band inversion algorithm. For the retrieval of subsurface properties, a time-domain inversion technique is employed together with a parameter optimization for the pulse shape of time delay echoes from VHF/UHF band radar observations. Numerical studies to investigate the accuracy of the proposed inversion technique in presence of errors are addressed.The numerical simulation of scattering from a cylinder buried in layered rough surfaces is then performed. ... In addition, the code is written in Matlab and the simulations are performed on a PC with Pentium-4 2-GHz processor and 1 GB RAM.
