This research is a progress report on a project funded by NNSFC (National Natural Science Foundation of China). An optimizing algorithm based on information gain is put forward for multisensor detection and classification of multitargets. We deem that the uncertainty in target environment can be quantitatively described by entropy, and that we can use decrease in entropy to represent information gain. In section 2 we discuss in much detail how to use entropy to obtain information gain and the optimizing algorithm of sensor management. Simulation results in Table 1 indicate preliminarily that, compared with sequence search algorithm, our optimizing algorithm can improve SNR (signal noise ratio) and reduce error probability.
