Abstract :
VHF/UHF dual-frequency and quad-polarized SAR (synthesize aperture radar) based on vector network analyzer is developed for measuring the soil moisture subcanopy and at depth. A discrete scattering model is used to simulate the scattering of vegetation. Rough surface layered media is as deep layered soil model. Semiempirical dielectric properties model of soil is used for soil moisture reversion. Simulation results are given.
