Description

A method and device for measuring the amount of multi-radar information based on information entropy technical field Embodiments of the present invention relate to the technical field of data processing, in particular to a multi-radar information volume based on information entropy measurement method and device. Background technique In practice, the battlefield environment and targets are constantly changing, and the multi-radar system resources need to be Sources, including radar station placement, radar parameters and fusion methods, are dynamically organized in real time to adapt to changing complex environments And the target, so as to maximize the acquisition of target information, to achieve the best target detection, tracking or recognition. [0003] Generally speaking, the detection system interacts with the target environment to obtain information to reduce the uncertainty of the target environment. The radar nodes of the distributed multi-radar system are w...
