The Study Of Multisensor Information Fusion Technique

In modern C3I systems, information provided by single sensor can't be satisfied by the need of modern war. Multisensor must be used to provide measure data, detect and identify object in real time, optimize colligate manage results. Therefore technology of multisensor information fusion developed rapidly, and was widely applied to modern C3I systems and weapon flat roof.The paper constructed every level information fusion models firstly, and put emphasis on position level fusion and identification level fusion arithmetic. In position level we discuss multiradar system, infrared sensor and radar tracking fusion arithmetic. The data processing of multiradar system is: coordinate transforming, data fusion, tracking arithmetic. The arithmetic idea of infrared sensor and radar tracking fusion is: getting solar by infrared image processing, time matching, synchronization fusion with radar data, updating object state by fusion data filtering. We can found from computer simulation result that the tracking precision improved by information fusion, mobility was responded in short time. In object identification level object identification fusion based on D-S proof theory was discussed, performance analyzing is found that the arithmetic did not need probability distribution. The fifth chapter discuss network of information fusion system. According to the characters of information fusion system Ad hoc net protocol was imported, and its feasibility was discussed.
