A Target Tracking Algorithm Based on Fusion of an Infrared Sensor and a Two-dimensional Radar

A new integrated tracking system based on radar and infrared sensor is developed.Radar measures slant range,azimuth and elevation,and infrared sensor measures azimuth and elevation accurately.Data fusion techniques is employed to get maximum likelihood method estimates and to improve the tracking performance.When radar cannot actively work this paper applies the bearing time difference location method to deal with the passive location problem of the maneuvering target,and then adopts data fusion technique to improve further the location tracking accuracy.The simulation results indicate that the method is effective and feasible.
