Detecting sub-surface objects poses significant challenges, partly due to attenuation of the ground medium and cluttered environments. The acquisition polarisation and antenna orientation can also yield significant variation of detection performance.

In 2017 it will be Australia's turn to chair the Kimberley Process Certification Scheme (KP), an international organisation set up to regulate the trade in diamonds. Diamonds are a symbol of love, purchased to celebrate marriage, and it is therefore

The design and subsequent testing of suitable antennas and of complete ground-penetrating radar (GPR) systems can be both time consuming and expensive, with the need to understand the performance of a system in realistic environments of great importa

2017 9th International Workshop on Advanced Ground Penetrating Radar (IWAGPR).
The simulation software gprMax uses the Finite Difference Time Domain (FDTD) method to model propagating electromagnetic (EM) waves primarily for the purpose of ground-penetrating radar (GPR). This open source tool provides a means to investigate the

A numerical modelling case study is presented aiming to investigate aspects of the applicability of artificial neural networks (ANN) to the problem of landmine detection using ground penetrating radar (GPR). An essential requirement of ANN and machin

Proceedings of the 15th International Conference on Ground Penetrating Radar.
A finite-difference time-domain (FDTD) algorithm is used to model and study the performance of ground penetrating radar (GPR) for anti-personnel (AP) landmine detection. A novel algorithm is proposed which creates the geometry of the vegetation for b

Conventional metal detectors are established and trusted tools for landmine detection, but their inability to precisely locate a target and discriminate mines from clutter leads to a high false alarm rate and slow rate of progress. This paper reports

This paper presents and compares two established methods for the automatic detection of landmines in ground penetrating radar (GPR) data. B-scan data of standard GPR targets and simulant landmines were collected from indoor sand and soil lanes. The i
