摘要: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 ofinteractive 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, maneuvering 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.%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.
