摘　　要：针对空间目标与恒星的近距离强干扰和瞬间遮挡干扰,不易精确捕获目标位置的问题。提出用卡尔曼滤波预测目标位置并跟踪目标,跟踪波门用改进自适应的可变波门。同时设计新的强干扰和瞬间遮挡目标的预判和跟踪方法,当预判到此类目标时,将卡尔曼滤波的预测值作为观测值跟踪目标,并用目标预测质心对波门质心进行限定修正,从而捕获有用的观测数据。实验发现,该方法能稳健跟踪强干扰和瞬间遮挡目标,提升空间目标的跟踪精度,降低数据错误率,提高数据质量,为捕获轨道位置提供更多更有用的数据。该方法程序运行速率快,具有一定的适用性和科学价值。It is difficult to accurately capture the target position due to the close strong interference and instantaneous occlusion interference between space targets and stars.Kalman filter is proposed to predict the target position and track the target,and the tracking gate is improved adaptive variable gate.At the same time,a new prediction and tracking method for strong interference and instantaneous occlusion targets is designed.When such targets are predicted,the predicted value of Kalman filter is used as the observation value to track the target,and the target prediction centroid is used to limit the correction of the gate centroid,so as to capture useful observation data.The experiment shows that the method can track strong interference and instantaneous occlusion targets robustly,improve the tracking accuracy of space targets,reduce data error rate,improve data quality,and provide more useful data for capturing orbital positions.This method runs fast and has certain applicability and scientific value.
