A NEW DUAL SENSOR DESIGN FOR ELONGATED CABLES/IEDS DETECTION USING EMI AND GPR

Abstract

A various GPR configurations can be used to detect buried elongated cables but it arises an inconsistent detection capability from ground clutter effects and many different objects in the ground. To address this issue, we propose a dual sensor configuration including EMI and GPR systems which distinguishes kinds of buried objects and reveal only cable detection. The system utilizes a special arrangement combining EMI and GPR signals to detect shallowly thin cables. While the proposed system has been less affected from other objects in the ground, so it has estimated the cables with high accuracy. The system has been produced a low cost and high efficiency design using STM32H743 microcontroller to control sensors and process and visualize the signals. The system performs robust and accurate cable/IED and landmine estimation. The effectiveness of cable/IED detection performance has been demonstrated using experimental data. The system detects cables 0.5 mm(2) thickness and above.
