Data Association in Multisensor Multitarget Detecting

The problem of data association in multisensor multitarget detecting is studied in the case of no clutter, missed detections, and an unknown number of targets. The association problem is formulated as a multiple dimensional assignment problem in combinatorial optimization, which is known to be NP hard. A new association algorithm based on GA is presented to solve the problem. Finally, the simulation results showed that the algorithm improved the detection probability of multisensor system for its higher association accuracy, and optimized the number of targets to be detected.
