휴대용금속탐지장비 성능 평가 연구

초록

Purpose: This study was aimed at evaluating the performance of domestic handheld metal detectors to identify the factors that influence the competitiveness of these devices. Methods: To evaluate the performance of such detectors, the test items were determined and test methods were established. Subsequently, detection, environmental, and magnetic field tests were conducted. Results: In the detection test, the detection performance did not satisfy the criteria when the detectors were 3.0 cm from the object. The detection performance of detectors based on nonferrous metals was inadequate. In the environmental tests, the detection performance did not change considerably with the detection environment. The safety standards were satisfied in the magnetic field tests. Conclusion: To enhance the competitiveness of domestic handheld metal detectors, the detection performance, especially that of devices based on nonferrous metals, must be improved. To more accurately identify the factors influencing the competitiveness of these devices, research must be performed at the subsystem and module levels.
