Next Generation Gate Sensors for Human Safety & Dynamic Operation

This thesis explores the implementation of millimeter-wavelength pulsed coherentradar in electronic gate systems to enhance safety and operational efficiency innoisy environments, such as retail stores. Current gate systems are predominantlybased on ultrasonic sensors, which are susceptible to environmental interference,leading to unreliable behavior and potential safety hazards. A radar-basedsolution was developed and tested that incorporates custom software for distancemeasurement, dynamic gate timing, and cross-traffic filtering. Experimentalresults demonstrate improved reliability in detecting human presence and intent,while also reducing unnecessary gate openings and ensuring safe operation. Thefindings suggest radar-based systems as a viable and superior alternative toconventional systems, with promising implications for broader applications inaccess control systems.
