Security assistant system combining millimetre wave radar sensors and chemical sensors

Abstract

This contribution describes a security assistant system comprising distributed millimeter wave radar sensors and chemical sensors. The system is deployable for a wide range of security applications, e. g. passenger security checks on airports, surveillance of people crowds in mass transportation systems or in other security-sensitive areas. The system looks for body-worn hazardous chemical substances in two steps: At first, distributed chemical sensors detect traces of chemicals in a tight tunnel in which multiple persons move freely. These measurements are repeated at different locations whereby the person carrying the chemical can be determined. Afterwards, the radar module scans the person to be screened and yields as the result the exact location of the detected explosive on the body. This facilitates a time-saving manual follow-up check by security staff. In this paper, the main focus is on the system set-up and millimeter wave radars for object imaging

Optimized Real-Time Tracking Radar Trajectory Simulation with Multi-Threaded Data Transmission and Visualization

“…Moreover, expanding the simulator's functionality to support additional RADAR modes and scenarios would broaden its applicability and utility in diverse contexts. [12] Furthermore, incorporating interactive features and customizable parameters would offer users greater flexibility and control over simulation settings, catering to a wider range of research and training needs.…”

A broadband coplanar waveguide to WR4 contactless transition using interdigital‐pin electromagnetic bandgap structure

“…With the development of millimeter‐wave (mm‐Wave) and terahertz (THz) technology in modern wireless communication systems, mm‐Wave hybrid integrated circuits and monolithic integrated circuits have been widely used in communications, 1 radar, 2 guidance, 3 and other systems 4 . Coplanar Waveguide (CPW) is an important transmission line in the mm‐Wave integrated circuit which has the advantages of small dispersion, low loss and easy to realize the series and parallel of passive and active devices 5–7 .…”
