精密仪表着陆系统能够为飞机提供垂直引导和水平引导,通过虚拟下滑道引导飞机进近降落。利用FEKO软件对ILS航向天线和下滑天线进行建模,计算得到信号辐射特性。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。针对华北某新建支线机场制定ILS台站选址方案,消除周边信号遮蔽和信号干扰,选址结果表明ILS台站满足后期校飞和飞行运行要求。

Precision Instrument Landing System can provide vertical guidance and lateral guidance for the aircraft, guide the aircraft approach landing through a virtual glide path .According to the radiation characteristics, ILS antenna is modeled by the electromagnetic simulation software FEKO. The course surface is structured by the characteristic that CSB and SBO signals are strongest at direction of centerline of the runway extension cords, so the glide slope is obtained by intersecting with glide surface. The simulation shows the accuracy of the approach and landing optimal control by ILS simulation. The navigation siting plan is developed for a new regional airport. Eliminate the signal shielding and signal interference, the result shows the navigation beacons satisfy the airport operation requirements.
