摘　　要：探讨了水平非均匀表面波导条件下的非互易性。基于信道互易性和对流层波导的研究背景,利用马尔科夫过程模拟波导水平非均匀特性,结合抛物方程理论方法以及计算机模拟生成数据,仿真分析了雷达电磁参数、大气波导参数等对电波传播特性的影响。仿真结果表明,表面波导非互易性的影响在波导水平非均匀条件下无法忽略,雷达参数的取值对非互易性的影响较大。This paper discusses the non-reciprocity of surface duct on the condition othorizontal non- unitormity. Based on channel reciprocity and tropospheric duct, by applying Markov process to hori- zontal non-uniformitycharacteristics simulation, the paper analyzes the impact of radar electromagnet- ic parameters and atmospheric duct parameters on wave propagation characteristics, combined with- the parabolic equation theory method and data generatedby computer simulations. Simulation results show that non-reciprocity can not be ignoredwhen the surthce ductis horizontally inhomogeneous, while the values of the radar parameters have great effects on the non-reciprocity.
