Ground-Penetrating Radar(GPR) system can detect buried objects such as underground cavities and mines by emitting electromagnetic waves and visualizing signals reflected from underground facilities by emitting electromagnetic waves.But in order to distinguish buried objects, it is necessary to understand signal patterns for each target and it is difficult to detect signal patterns for each target in real time.In this study, adaptive signal processing technique is applied to reduce the effect of non-uniform clutter signals on images to increase the visibility of target signals, and energy profile extraction technique is used to simplify the identification of target signals.In addition, the 2.5D template matching technique is applied to calculate matching rate of the detected object.Several objects selected in soil-filled test sites were buried in various locations to confirm their performance through real-time detection software, and it is expected to be applied to mine detection systems using real-time automatic exploration in the future.
