Abstract  

The presence of young stand cover alters the signatures that directly come from bare frozen soil surface.Matrix\|Doubling model is a complex passive microwave model to simulate the radiative transfer and attenuation properties of vegetation covers.In this paper,the Matrix-Doubling model is revised so that it can be used at frozen environment.The simulation results are then compared with experimental results obtained at Ku and Ka band by a truck-mounted dual-polarization microwave radiometer.In the end,the complex model (M-D model) was matched with the simple model (τ-ω model) under the same environment.In this way,the young stand effects on soil surface microwave radiation signal are eliminated.
