摘要
在分析进近着陆系统多径效应问题的基础上,提出利用电磁散射算法模型建立机场复杂环境的散射体模型库,通过不同特性散射体调用各自有效算法模型的方法,实现了进近着陆系统开阔场多径效应仿真,并利用IPO算法模型对停靠飞机多径效应进行了仿真,仿真结果证明了基于模型库的进近着陆系统多径效应仿真方案的可行性。
Based on the instruction of the multipath effect of the approaching landing system, the construction of the scatter model database for the complex environment on the airports was completely demonstrated. According to the principle of electromagnetic scattering arithmetic, different scatters select different model. On the other hand, the aircraft diffraction and reflection was simulated correctly. The result indicates that the calculation coincides with the measured result.The feasibility of the proposal in system simulations is proved.
