摘要

中文摘要: 为了解决高密度飞行环境下航空器对的短期冲突虚警问题，研究了航空器当前位置和速度矢量的相互关系，证明了只有位置差与速度差矢量内积小于零的航迹对才具有潜在冲突，并根据安全飞行间隔规定，采用线性预测方法对其进行冲突有效性确认，实现快速有效的短期冲突检测。通过模拟试验下的监视雷达数据，验证了本文算法的有效和准确性，相对于其他算法，本算法快速准确的实现了高密度飞行情况下潜在短期冲突航空器对的检测，并解决了当航空器背向飞行时不再进行告警的问题，减少了地面管制人员的工作量。

Abstract

Abstract:For decreasing the false alert in high flight density

we researched the position-velocity vector for aircraft pairs

and proved that only the pairs which inner product of difference vectors of position and velocity was less than zero would be in unsafe state. According to the flight rules

the pairs were be confirmed by linear prediction. Many scenarios via simulation surveillance radar data were demonstrated and the results showed that it was more useful and reliable for high flight density situation

and especially in reducing the false alert for opposite flying aircraft
