Abstract: A method of the multi-target locating and tracking modeling with the laser warner is studied. The clustering concept is applied to the measurements of the laser warner,and space-time fusion for the measurements in the same cluster is made.The synchronous -pulse-control logic in real time is formed by solving estimated tracking data fusion parameters to implement the real time tracking of multi-laser-target and the real time picking of multi-laser signals. The design process for the multi-target locating and tracking with the laser warner is introduced,a practical algorithm is presented ,and a prototype device is built. The results of experiments show that the method is very effective.
