Abstract

The invention discloses a target detection method and device, a radar and a storage medium. The method comprises the following steps: acquiring detection parameter information of a radar on a target tunnel, and determining electromagnetic wave signal parameters of the radar based on the detection parameter information; controlling the radar to transmit a target electromagnetic wave signal matched with the electromagnetic wave signal parameter to the target tunnel; and receiving an echo signal corresponding to the target electromagnetic wave signal, and determining target detection information corresponding to the target point cloud based on the echo signal. Through the technical scheme provided by the embodiment of the invention, the resolution capability of the radar on a real target and a multi-path target in the tunnel can be improved, so that the detection precision of the target is improved.
