摘要 在民航飞行着陆优化控制问题的研究中,着陆阶段作为飞行器运行的最后环节,对飞行安全至关重要。由于气候条件、导航信号受到电磁干扰影响,使飞行员难以准确着陆。为此,对进近着陆系统采用仪表着陆系统(Instrument Landing Sys-tem,ILS)的航向天线特性,结合全球地理信息系统,采用ILS对飞行器终端区进近着陆支持的三维可视化方法。可依据ILS天线的辐射特性和电磁仿真软件,对ILS天线进行建模。根据航向天线的CSB和SBO信号在跑道中心线延长线方向最强特性得到航向面,与下滑面相交得到下滑道,并进行仿真。仿真结果证明了仿真ILS对飞行器的终端区进近着陆优化控制的准确性,表明改进方法的结果符合飞行器终端区进近着陆的要求,可以为民航机场在布设ILS台站和飞行校验时提供可靠的三维空间参考。 In the research of optimal flight control problem of the civil aviation landing, landing stage is critical to flight safety as the last link of the vehicle running. Due to climatic conditions and navigation signals by electromagnet- ic interference, the pilots can not accurately land. Localize antenna radiation characteristics of Instrument Landing System (ILS) were used for landing system, and a three-dimensional visualization method was proposed to simulate the supporting situation of ILS to the approach and landing of aircraft in terminal area combine with GIS. According to the radiation characteristics, ILS antenna was modeled with the electromagnetic simulation software. The course sur- face was structured based on the characteristic that CSB and SBO signals are strongest at the direction of centerline of the runway extension cords, so the glide slope was obtained by intersecting with glide surface. The simulation shows the accuracy of the approach and landing optimal control by ILS simulation. The result of the proposed method satis- fies the requirements of aircraft approach and landing in terminal area. So the method can provide reliable three-di- mensional spatial reference information for locating ILS station and flight inspection at civil aviation airport.
