Estimation of Lane Width for Object Detection Using Impulse GPR with “1Tx and 4Rx” Antenna System

This paper reports on an experimental study of object detection and location using UWB Impulse GPR with a specialized “1Tx and 4Rx” antenna system. Algorithms for data collection and processing are described. The results of the study demonstrate the ability of the radar to cover a lane width of more than 60 cm with the antenna array at a height of 37 cm. Within the lane the system can readily detect an antipersonnel landmine simulant. Preliminary analysis of laboratory testing data (in air) has also shown the capability of the proposed processing to estimate the distance between the object and each Rx antenna with an accuracy of 0.8 cm for distances up to approximately 40 cm.
