| 摘 要： | 从经典混响室的平面波叠加模型出发，针对已有的概率统计模型不能模拟莱斯分布场环境的情况，建立了改进型的平面波叠加模型。为了验证该模型的有效性，用蒙特卡洛方法仿真了不同K因子下的各场量的概率密度函数(PDF)，并用理想PDF进行拟合。并进一步验证了当莱斯K因子为零时，莱斯分布场模型退化为经典混响室的场模型。最后考虑了模型的抽样参数(平面波叠加数和搅拌器位置数)对仿真结果的影响，确定最佳的抽样样本，从而获得稳定的PDF曲线。

| Abstract: | Based on the plane wave superposition model of the classical reverberation chamber, an improved plane wave superposition model is established in view of the fact that the existing probabilistic statistical model cannot simulate the environment of electromagnetic field with Rician distribution. In order to verify the validity of the model, the Probability Density Function(PDF) of the related electric field under different K factors is simulated by Monte Carlo method and fitted with ideal PDF. It is further verified that when the Rician K factor equals 0, the Rician distribution electromagnetic field model degenerates into a classical reverberation chamber field model. Finally, the influence of the sampling parameters(plane wave superposition number and agitator position number) on the simulation results is considered, and the best sample is determined to obtain stable PDF curve. |
