Adaptive antidromic window moving method for spacecraft orbital maneuver detection
Using two line elements as data source,an adaptive method using antidromic window moving for detecting maneuvers of space objects was proposed.Adaptive window configuration model was established to get detection window for different objects.Meanwhile,cross arc prediction was integrated in order to obtain the maneuver time more precisely.Applying antidromic window moving method,the maneuver in the latest epochs can be detected.The results were compared with real maneuvers as well as in the existing literature.It is shown that the proposed method can adapt to the window configuration of maneuvering detection of space objects on different orbits.Besides,the detection success rate can reach more than 90%under the given simulation conditions.Moreover,the accuracy of maneuver time estimation is observably higher than that of existed method.Simulations of the approach proposed have demonstrated good performance in near-real-time maneuver detecting.
