中文摘要:
      针对现有蒸发波导条件下线电系统性能研究过程中,忽略了蒸发波导水平非均匀特性影响,探讨了水平非均匀蒸发波导条件下的非互易性。利用马尔科夫过程模拟蒸发波导水平非均匀特性,结合抛物方程法计算电波传输损耗,仿真分析了雷达电磁参数对非互易性的影响。仿真结果表明:蒸发波导环境下电波传播的非互易性在波导水平非均匀时法忽略,天线高度和电波频率对非互易性的影响较大。天线高度越高,电波频率越大,则非互易性越强。
英文摘要:
      For the problem of ignoring the horizontal inhomogeneous characteristics of evaporation duct in the research of radio system performance, the non-reciprocity of evaporation duct on the condition of horizontal inhomogeneous environment is discussed. The non-uniformity characteristics are studied by the simulation of Markov process. Radio transmission losses are calculated by parabolic equation method. The impacts of radar electromagnetic parameters on non-reciprocity are analyzed. Simulation results show that the radio non-reciprocity cannot be ignored in the horizontal inhomogeneous evaporation duct environment, the effects on non-reciprocity of antenna height and frequency are great. The larger the antenna height and the radio frequency, the stronger the non-reciprocity.
