[0034] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.
[0035] In the multi-radar hybrid detection method based on information entropy proposed in the present invention, the multi-channel echo signals are respectively subjected to square law detection and information entropy detection, and the output detection result is determined by the "or" decision criterion to determine whether there is a target. When the square law detection or When the information entropy detects the target, the judgment result is that there is a target, so that a good target can be detected under different channel SNR differences.
[0036] For the convenience of description, the multi-radar dual hypothesis test model is set as follows in this implementation.
[0037] Each radar in the multi-radar...
