Abstract:

Regarding the trajectory tracking and trajectory prediction of near space hypersonic targets with fast time-varying maneuver properties, based on the existing motion model for slowly time-varying maneuvering targets, a state quantity describing the characteristics of fast time-varying maneuvers is introduced to establish a nonlinear model for maneuvering target tracking, firstly. It is proved that the nonlinear tracking filter system based on this model is observable. Secondly, aiming at this system, a hybrid continuous-discrete measurement interpolation fast convergence generalized Kalman filter is proposed. A target maneuvering pattern recognition method based on cluster analysis is also proposed, and a predictor based on target maneuvering pattern recognition is designed. Simulation results show that for near space hypersonic vehicle performing fast time-varying maneuvers, the maneuver model proposed can obtain good tracking and prediction results.

Key words: near space, hypersonic vehicle, fast time-varying maneuver model, cluster analysis, trajectory prediction
