Sampling Interval Parameter Design Based on Active Millimeter Wave Imaging

Millimeter wave has good penetration and security, which can be better applied in security check system. The security check system needs to consider the imaging time and resolution, so it has great significance to rapidly reconstruct the imaging and improve the resolution for active millimeter-wave imaging. In this paper, the design of millimeter wave reconstruction imaging sampling interval is studied. Through analysis and experiment, the sampling interval is optimized, and the imaging results of traditional millimeter wave reconstruction algorithm and accurate millimeter wave algorithm are verified, which provides a theoretical basis for the design of active millimeter wave imaging system.
