This disclosure relates to the technical field of decoy targets. One embodiment of this disclosure provides a decoy target that can be quickly folded and deployed, comprising: a main frame and a target plate, the target plate being disposed on the main frame, an adjustment assembly being disposed on the main frame, and a deployment assembly being disposed between the main frame and the target plate. The deployment assembly includes a transmission cavity, which is formed on the surface of the main frame. An extension frame is movably connected to one end of the transmission cavity. A pair of connecting rods are provided at both the upper and lower ends of the transmission cavity. One end of the extension frame is movably mounted on the connecting rod, and a spring is mounted on the connecting rod. The spring supports the extension frame between the inner end face of the transmission cavity and the connection rod. This technical solution solves the problem that existing decoy deployment mechanisms often rely on a single spring drive or hydraulic push rod, which can easily lead to component jamming and further prolong the deployment time in harsh environments such as low temperatures and sandstorms, failing to meet the needs of modern rapid-response warfare and efficient training.
