Several approaches to the detection of Unexploded Ordnance (UXO) in the ground are discussed. Methods exploiting the coupling of sound into the earth are shown to have promise. These approaches can use both linear and non-linear phenomena as clues. Also discussed is the potential of a ground penetrating radar method that is based on a nonlinear phenomenon.

Objective: The objective of the current research is to work towards resolving issues that affect sonar detection and classification/identification (C/ID) of underwater UXO using sonar. Background: Based on extensive assessments of other sensor technologies carried out at NSWC PCD for underwater Navy applications, sonar is expected to play an indispensible role in underwater UXO remediation. Aco...

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...

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...
