The Naval Explosive Ordnance Disposal Technology Division (NAVEODTECHDIV) is conducting an exploratory development program for the development of small, inexpensive, robotic technologies that enable systems that will clear unexploded submunitions and mines from contaminated land areas. The concentration is on control methodologies to enable teams of small autonomous robots to work together to p...

background: although in the last few years there has been an increasing attention to the problem of landmines, to date, the implications of women being victims of landmine has not been duly dealt with in the world including iran, which is estimated to be the second most landmine infested country in the world. still, provinces by the west border of iran, 18 years after cessation of iraq-iran war...

The detection of dipole-like sources, such as unexploded ordnances (UXO) and other metallic objects, based on a magnetic gradiometer system, has been increasingly applied in recent years. In this paper, a novel dipole-like source detection algorithm, based on eigenvector analysis with magnetic gradient tensor data interpretation is presented. Firstly, the theoretical basis of the eigenvector de...

Military activity has resulted in unexploded ordnance (UXO) existing the nearshore. Understanding and predicting UXO behavior is important for object identification, management. Here, two studies (laboratory fieldwork) have been conducted to observe surrogates swash zone relate burial migration underlying forcing conditions. A small-scale laboratory dam-break study was quantify of varying densi...

The millions of pieces of unexploded ordnance (UXO) littering former battlefields are a lingering legacy of World War I. In the Verdun, French démineurs dispose of about 30 tons of chemical ordnance each year; they have been doing so since 1945. China, too, has a chemical battlefield legacy, with more than 120 tons of abandoned Japanese chemical weapons from World War II. The removal of these w...

Magnetometry has emerged as an effective tool for UXO discrimination. The current approach is based upon the magnetic dipole moment recovered from the inversion of surface total-field magnetic anomalies. However, the reliability of inversion will be strongly influenced by the noise in the data such as that produced by magnetic soils in the background geology. We examine this problem to understa...

Abstract: This paper describes our approach of applying clustering techniques in the detection of UXOs (Unexploded Ordances). The clustering algorithms help us to integrate information from various sensors. Because of the specific characteristic of our application, a new MLE (maximum likelihood estimation) method is designed. The MLE is integrated into the clustering algorithm whose inputs are ...

Landmine clearance is an ongoing problem that currently affects millions of people around the world. This study evaluates the effectiveness of ground penetrating radar (GPR) in demining and unexploded ordnance detection using 2.3-GHz and 1-GHz high-frequency antennas. An automated detection tool based on machine learning techniques is also presented with the aim of automatically detecting under...
