Abstract： The lag of maneuvering target tracking results on the time axis is a major difficulty in the field of maneuvering target tracking. There are many cases of time delay, which are especially obvious in the early stage of tracking and the time period when a large maneuver occurs, and there is often a peak of error because of this, if there is a way to suppress or eliminate the time delay phenomenon, the tracking effect will be significantly improved. Starting from the results and phenomena of simulation experiments, combined with Kalman filter theory, interactive multi-model algorithm and modern neural network model, this paper will deeply analyze the time delay problem, and obtain different causes of time delay according to the changes of each stage of tracking and give corresponding solutions, so as to provide reference for improving the tracking effect of maneuvering targets in the future.
