Abstract

Measuring many people within a short time is still a great challenge to scanners in security related areas, e.g. airports or stations. A new approach for fast and high resolution scanning is presented, based on the so called "circular synthetic aperture radar" (CSAR), applied to a walkway. Due to the circular movement, each of the receiving antennas creates a circular synthetic aperture itself. By reconstructing the complex valued SAR-images for each receiver channel, the ability to perform interferometric SAR-Analysis of a tested person is given. The screened persons do not have to stand still, thus, a measurement in a passenger flow is possible.
