MIMO technique can improve the spectral efficiency and increase the system capacity of the satellite mobile communication system, and the modeling of dual-polarized satellite mobile MIMO channel has been a hotspot issue. In order to take the advantage of the low complexity of the statistics channel model and the high acuuracy of the geometric model, geometric statistics based modeling theory of dual-polarized satellite mobile MIMO channel is proposed in this paper. The geometric statistics based model applies ray tracing method to each MIMO path, and calculate the parameters of the rays with statistical methods. The simulation results of the first and the second order statistical characteristics are given in the paper, and the geometric statistics model of dual-polarized satellite mobile MIMO channel is verified. Also, the conclusion that the model can improve the accuracy of the simulation of dual-polarized satellite mobile MIMO channel effectively is drawn.
