航迹插值在无人飞行器电磁干扰分析中的应用

Application of Moving Track Interpolating Methods in Electromagnetic Interference Analysis of Unmanned Aerial Vehicle

为了提高空中飞行器飞行系统的稳定性,必须确保航迹上电磁干扰分析结果正确,因此需要对不够密集的相邻航路点之间的航线进行插值。根据飞行器的飞行特点和电磁干扰分析性能的要求,给出了大圆航线上等距离和等角航线上等距离两种插值方法,并给出了两种方法的原理和仿真流程。结果证明,两种方法的应用确保了电磁干扰分析结果的准确性,大大提高了空中飞行器系统的稳定性。插值方法的应用为飞行任务可靠地执行提供了有力的保障。

In order to improve the stabilization of UAV system, the result of Electromagnetic Interference analysis must be correct, so the track built up by the fairway point must be interpolated. According to the flying characteristics of unmanned aerial vehicles（UAV） and the performance requirement of Electromagnetic Interference, two interpolating methods are adopted, one is the same distance interpolating method on Grear Circle, and the other is same distance interpolating method on Rhumb Line. The algorithm principles and program flows are given. The result demonstrates that the appliction of these mothods insures the veracity of analysis result and greatly improves the stabilization of the UAV. Appliction of interpolating methods provides effective support for the reliable execution of flight task.
