摘　　要：针对某些因轨道信息不完整而无法直接外推的LEO轨道飞行器的机动检测问题,提出了一种基于轨道摄动影响的面内机动检测方法。该方法将半长轴和偏心率作为检测量,通过分析大气阻力摄动和J2项摄动对LEO飞行器轨道的影响,从而确定目标飞行器的轨道参数允许边界值,再通过和实际轨道参数进行比较来判定被检测数据点参数是否超出正常范围。最后,采用这种方法对X-37B飞行器轨道数据进行了仿真验证,共检测出10个机动点,结果表明该方法可以较为准确地利用有限轨道信息检测目标的轨道机动情况。An in-plane maneuver detection method based on orbit perturbation is proposed in this paper to solve the maneuver detection problem of incomplete orbit information of LEO spacecraft that can＇ t propagate directly. Semi-major axis and eccentricity are chosen as characteristic parameters in this method. The orbit parameter boundary of target spacecraft is established by analyzing the effect of atmosphere perturbation and J2 perturbation on LEO spacecraft orbit. By comparing with the actual orbit parameter, whether the data point detected is in the normal boundary can be judged. At last, the orbit parameter of X-37B is detected by this method, and 10 maneuver points exist. The detection result has demonstrated the effectiveness of the approach proposed.
