It is a challenging problem to track point source targets and small extending ones in clutter. Only using single-image sensor is usually not adequate to meet the requirement of a multi-target tracking (MTT) system. Carrying out the measurement through two IR waveband image sensors, and fusing efficiently measurement data of both sensors, we can track small extending targets precisely and improve the performance of the MTT system. In this paper, the multi- target tracking method based on 3-5 micrometers and 8-12 micrometers IR image sensors is introduced. The mission scenario is thought as tracking air target. The algorithm of the target image centroid estimator is discussed. In order to improve the precision of target tracking, the data fusion algorithm with Kalman filter is described for the target vector feature. THe simulation results indicate that the target tracking precision can be improved by tracking small extending targets with dual-IR image sensors.
