Freehand millimeter-wave imaging system based on a highly-integrated MIMO radar module

7 April 2022 • 8:50 AM - 9:10 AM EDT

Abstract

In this contribution, a portable freehand millimeter-wave imaging system based on a commercial highly integrated radar-on-chip is presented. The portable imager, whose position is tracked during its operation, is moved by hand over the inspected area, enabling versatile screening capabilities with a compact device. The movement of the scanner is leveraged to create a synthetic aperture, resulting on an increased lateral resolution of the system, which comprises up to 400 independent radiofrequency channels. The performance of the proposed freehand imaging system, which is capable of providing high-resolution images at a fast acquisition rate, is illustrated through measurements of different targets.
