摘　　要：针对纯方位目标转向机动检测问题,提出一种基于航向估计的多平台纯方位目标机动检测算法。该算法通过选定假设机动点序列,解算假设机动点前后的两段目标运动要素,根据解算出的相邻段航向差序列变化来判别目标是否发生机动。基于Taylor级数要素解算模型,建立了两段运动要素联合解算模型和两段运动要素独立解算模型。通过对多种航路进行仿真计算,统计分析这两种解算模型下机动检测算法的虚警率、目标机动检测率、机动检测延迟时间以及机动时刻估计精度。仿真结果表明,两种解算模型下的机动检测算法能够有效地对转向机动目标进行机动检测。Aiming at the problem of bearing-only target steering maneuver detection,a multi-platform bearing-only target maneuver detection algorithm based on heading estimation is proposed.The algorithm selects the sequence of hypothetical maneuvering points,solves the two target motion elements before and after the hypothetical maneuvering point,and determines whether the target maneuvers according to the change of the sequence of the heading difference of the adjacent segments solved.Based on the Taylor series element solution model,a joint solution model of two motion elements and an independent solution model of two motion elements were established.The false alarm rate,target maneuver detection rate,maneuver detection delay time and maneuver time estimation accuracy of the maneuver detection algorithm under these two solution models are statistically analyzed.Simulation results show that the maneuver detection algorithms under the two solution models can effectively detect maneuvering targets.
