已有混响室概率统计模型不能同时模拟多种多径衰落场环境.通过扩展经典混响室平面波叠加模型,建立了更具普适性的混响室内模拟多径衰落场环境的概率统计模型.推导了电场直角分量模值的概率密度函数(PDF),在理论上验证了新模型能同时模拟瑞利分布、莱斯分布及更多多径衰落场环境.通过蒙特卡洛模拟仿真了电场直角分量模值的PDF,并与理论PDF对比,进一步验证了新模型同时模拟多种多径衰落场环境的能力.
The existing probabilistic statistical model of reverberation chamber cannot simulate multiple multipath fading electromagnetic environments at the same time.In this paper,the classical reverberation chamber plane-wave superposition model is extended to establish a more generalized probabilistic statistical model for simulating multipath fading field environments in reverberation chambers.By deriving the probability density function(PDF)of the magnitude of the rectangular component of the electric field,it is theoretically verified that the new model can simultaneously simulate the Rayleigh distribution,Rician distribution and more multipath fading electromagnetic environments.The PDF of the magnitude of the rectangular component of the electric field is simulated by Monte Carlo simulation and compared with the theoretical PDF,which further verifies the ability of the new model to simulate multiple multipath fading electromagnetic environments simultaneously.
