Abstract
In this paper, based on analysis principles of millimeter-wave near-field wideband array holographic imaging techniques, millimeter-wave near-field holographic imaging system is recommended. Its principle is that a millimeter-wave radiation launches the millimeter-wave signals, then the echo reflected from the target to interface with the original signal, the millimeter-wave holograph has been got. Finally, the millimeter-wave holograph treatment with algorithms such as Flourier Transform, compensation and image restoration, it obtains the millimeter-wave image of target. Millimeter-wave near-field holographic image has high speed, high resolution and strong three-dimension sense, which has broad application prospects in concealed weapons detection.
