摘要:
Target maneuver trajectory prediction plays an im-portant role in air combat situation awareness and threat assess-ment. To solve the problem of low prediction accuracy of the tra-ditional prediction method and model, a target maneuver trajecto-ry prediction model based on phase space reconstruction-radial basis function (PSR-RBF) neural network is established by com-bining the characteristics of trajectory with time continuity. In or-der to further improve the prediction performance of the model, the rival penalized competitive learning (RPCL) algorithm is intro-duced to determine the structure of RBF, the Levenberg-Marquardt (LM) and the hybrid algorithm of the improved particle swarm optimization (IPSO) algorithm and the k-means are intro-duced to optimize the parameter of RBF, and a PSR-RBF neural network is constructed. An independent method of 3D coordi-nates of the target maneuver trajectory is proposed, and the tar-get manuver trajectory sample data is constructed by using the training data selected in the air combat maneuver instrument (ACMI), and the maneuver trajectory prediction model based on the PSR-RBF neural network is established. In order to verify the precision and real-time performance of the trajectory prediction model, the simulation experiment of target maneuver trajectory is performed. The results show that the prediction performance of the independent method is better, and the accuracy of the PSR-RBF prediction model proposed is better. The prediction confirms the effectiveness and applicability of the proposed method and model.
