Present state of the art in ground-penetrating radars for mine detection

Abstract

The U. S. Army has under development a number of systems to detect buried metallic and nonmetallic land mines. Almost all of these systems include a ground penetrating radar (GPR). These systems may be handheld or vehicle mounted and may be designed for close in or for standoff detection. A consensus has not been reached regarding many important system parameters. A discussion of the tradeoffs involving waveform, frequency, bandwidth, downlook angle, scanning methods, polarization, and spatial resolution will be presented. The usefulness of special techniques such as target resonances, synthetic aperture, and multiple polarizations will be discussed. The potential of GPR will be compared with competing sensors. A brief overview of a diverse set of GPR sensors will be presented.

Landmine detection from GPR data using convolutional neural networks

“…Specifically, object detection consists in individuating the presence of buried targets that represent a possible threat. Object classification is the process of discriminating objects of interest (e.g., landmines) from other buried targets (e.g., clutter) [2]. In this paper, we focus on the first step.…”

Generalized two-sided linear prediction approach for land mine detection

“…Owing to the capabilities of good penetration and depth resolution as well as detecting both metallic and nonmetallic objects, ground penetrating radar (GPR) [1] has been considered as a viable technology for land mine detection. A GPR system consists of a transmitter for emitting electromagnetic wave to the inspection surface and a receiver for collecting the returned signal from which the decision of whether there is a mine is made.…”

Context-dependent fusion with application to landmine detection.

“…with little or no metal content. Unfortunately, landmine detection via GPR has been a difficult problem [67,68]. Although systems can achieve high detection rates, they have done so at the expense of high false alarm rates.…”
