Abstract
This invention provides a security check apparatus for multiple human bodies based on linear frequency modulation, which comprises a scanning device, a millimeter wave signal transceiver module, and an image processing unit. The scanning device comprises several detection seats and several guideways and motors arranged on the detection seats; the detection seats are configured to accommodate persons to be security checked; a set of the millimeter wave signal transceiver modules are arranged on each guideway, and each millimeter wave signal transceiver module is driven by the motor to move along the guideway; the several detection seats are arranged in longitudinal direction. The millimeter wave signal transceiver modules are configured to transmit millimeter wave signals to the persons to be security checked and receive millimeter wave signals reflected from the persons to be security checked. The image processing unit is configured to perform holographic 3D imaging on the human bodies of the persons to be security checked based on the reflected millimeter wave signals to obtain 3D images of the human bodies. This invention also provides a security check method for multiple human bodies based on linear frequency modulation. This invention has the advantages of low cost, simple structure, easy integration, high resolution, more persons are detected per unit time, and no radiation hazard to human bodies.
