中文摘要
由于基站电磁辐射对飞行器的飞行安全构成潜在威胁, 本文提出了一种混合计算方法来研究城市微蜂窝小区上空电场分布情况. 该方法通过将城市微蜂窝小区电波传播模型和二维宽角抛物线方程方法相结合, 更加精确的计算出小区上空电场分布情况. 计算结果表明, 微蜂窝小区上空电场分布会受到小区布局的影响. 并且在小区上空, 出现多径快衰落现象. 计算结果为人们研制具有抗干扰能力的飞行控制系统提供了重要的电磁环境参数. 还可以帮助人们制定更加安全的飞行线路.
英文摘要
Since the underlying threat of base station radiation to flight safety of aircraft, a hybrid method is proposed to calculate electric field distribution above microcellular. This method could give more accurate calculation results by combining the radio wave propagation model of microcellular with the two dimensional wide angle parabolic equation method. Based on the calculated results, we find the layout of microcellular could influence the electric field distribution above microcellular. In addition, there exists multi path fast fading phenomenon above microcellular. The proposed method could help people to obtain significant electromagnetic environment parameters above microcellular for designing anti interference flight control systems and planning more secure flight paths.
