W波段近距离高分辨毫米波全息成像系统
W-band short-range high-resolution millimeter-wave holographic imaging system
摘要
Abstract
Millimeter-wave holographic imaging systems based on phase imaging have been extensively applied in fields such as security screening and non-destructive testing,due to their special penetration capabilities and high-resolution advantages.While extending operational frequencies to higher bands for achieving better resolution,the problems of dense transceiver arrangements and high system complexity need to be considered.This study presents a W-band short-range high-resolution millimeter-wave holographic imaging system utilizing linear array scanning.By implementing a 25-transmitter and 100-receiver array configuration with integrated electronic circuitry design,the system achieves high-quality short-range imaging across the 85～105 GHz operational band.Experimental results demonstrate the system can obtain spatial resolutions superior to 2 mm in the horizontal direction and 2.5 mm in the vertical direction at an imaging distance of 0.5 m,confirming its enhanced performance in practical applications.关键词
