Abstract:

Target track prediction is a key technology to ensure the navigation safety of the target, to plan the flight path and to search the air target. It is of great significance in military and traffic control. Aiming at the problem that the traditional air target track prediction method model is relatively simplified and the prediction accuracy is low, a deep neural network based on the Kalman filter algorithm for the air target track prediction task is proposed. The model uses long short-term memory (LSTM) network to learn the target motion model from the track data of air targets, and then uses the Kalman filter algorithm to dynamically modify the estimated target state generated by LSTM, which effectively combines the advantages of the Kalman filter algorithm and deep neural network. Experiments on simulation data and real data verify the accuracy and effectiveness of the proposed model compared with other networks models for air target track prediction.

Key words: Kalman filter, track prediction, long short-term memory (LSTM) network, algorithm unfolding
