The paper discusses a direct analytic solution of multisensor data fusion to avoid multiple iterative calculation of nonlinear differential equation

and the calculation amount is reduced

thus it raises solution efficiency of multisensor data fusion.The paper discusses performance control technique of sensor to ensure confidence and safety of multisensor data fusion.To raise detection capability of multisensor network for stealthy target

low-altitude flying target and target in jamming environment

the paper discusses multisensor adaptive detection fusion technique.The paper also analyses several advantages of sequential fusion for mobile target.
