摘要
在飞机冲突检测算法研究中,如何方便而又逼真的模拟冲突场景是需要解决的一个重要的问题。本文提出了一种基于通用航空飞机运动模型建立的多目标航迹生成方法。首先,基于通用航空飞机的性能参数与飞机运动模型描绘出各个飞行阶段的单个目标航迹,并构造三次B样条曲线插值于各分段航迹转折处,使单个目标航迹连贯而平滑。其次,参考FAA发布的DO-317文件中定义的典型冲突情况,生成多目标航迹,并设计出若干种冲突场景,为各种情况下的冲突解脱算法提供了理论验证基础。最后,将仿真场景应用到ADS-B IN应用仿真软件(AIAS)中,实验证明可以有效的检测出冲突检测算法的正确性。仿真软件以C#编程实现。
In the research of aircraft collision detection algorithm,one of the important problems is how to simulate conflict scenarios in a convenient and realistic method. A muti-target track generation method based on general aviation aircraft motion model is presented in this paper. Firstly,the single target tracks of various flight stages should be described based on the general aviation aircrafts＇ performance parameters and motion model. In order to make the target track be coherent and smooth,the cubic B-spline curve interpolation in the turning point of the track in each segmentis constructed. Secondly,refer to the definitions of the typical conflict scenarios in document DO-317 which is released by FAA,multi-target is generated and several conflict scenarios are designed to provide a theoretical basis for verification the conflict relief algorithm in each condition. Finally,put the simulation result into the ADS-B IN Application Software（ AIAS）,the results of the experiment in the software show the effectiveness of the collision detection algorithm and the simulation software is programmed by C#.
