摘　　要：为了提高航空器的短期冲突检测的准确性和可靠性,对传统算法与模型进行了研究,在此基础上设计了具有机动检测的交互式UKF算法,提出了短期冲突检测模型。该模型对飞行器的航迹进行了分析,然后对飞行器的冲突域检测、冲突脱离、机动检测和冲突确认进行了讨论,并根据该模型设计了冲突检测算法。仿真结果表明,该算法能够精确、实时的检测飞行器的航迹,克服了传统算法的冲突盲警告和轨迹不变问题,提高了冲突预警的准确性,为管制员提供了可靠的保障。In order to improve the accuracy and reliability of the aircrafts’short-term collision detection.The traditional algorithm and model are discussed,on the basis of which a mobile detection of interactive UKF algorithm is designed,the short-term conflict detection model is presented.The model analyzes aircraft s＇ flight path,discusses the conflict the domain of aircraft detection,conflict out,ma-neuvering detection and conflict identified,and designs the conflict detection algorithm according to the model.Simulation results show that the algorithm can detect accurately and real-time the state of aircraft,overcome the traditional algorithm conflict blind warning and path fixed,and improve the accuracy of the conflict warning,for the control personnel provide a reliable guarantee.
