SIL-Radar-based Rat Detector for Warehouse Management System
This paper presents a noncontact sensing system, which aims to detect a concealed rat in a non-metallic box at the shipping area to minimize the possibility of rodent infestation. The proposed architecture, capable of alternately switching the beam direction to detect different boxes at the same time, consists of a self-injection-locked (SIL) radar, a single-pole three-throw (SP3T) RF switch, and three panel antennas. With coherent sampling, the IQ signals while using different antennas are respectively paired for arctangent demodulation and output IQ phase. After subsequent processing with algorithm computed in both the time and frequency domains, the 2.4 GHz prototype is verified to detect the tiny movements of a concealed rat with a length of 6 cm, and the sensing distance from the box to the radar antenna is up to 50 cm.
