Development of Airborne Magnetic and Electromagnetic Systems for Mapping and Detection of UXO and Other Shallow Metallic Objects
نویسندگان
چکیده
Airborne geophysical systems have been in use since 1943 (Hildenbrand et al., 1990). These systems used airborne magnetometers for submarine detection and geophysical mapping. Airborne electromagnetic systems were introduced in the 1950s (Barringer et al., 1990) for mineral exploration. These early magnetic and electromagnetic systems were mounted on fixed wing aircraft. In the 1960s helicopter systems were introduced in which the electromagnetic components were mounted in towed birds, suspended from the helicopter on a cable, 30m or more in length.

Comparison of airborne magnetic and electromagnetic data from a bombing target
Airborne magnetic systems for mapping unexploded ordnance (UXO) and other shallow metals have been developed at Oak Ridge National Laboratory (ORNL) over the past five years .We have recently completed testing of a time-domain electromagnetic (EM) system to supplement the magnetic system for UXO investigations. The test was conducted at the Badlands Bombing Range (BBR) in South Dakota in Septem...

متن کاملA new–generation EM system for the detection and classification of buried metallic objects
A prime requirement in discrimination between UXO and non-UXO metallic fragments (clutter) is to determine accurately the response parameters that characterize a metallic object in the ground. Lawrence Berkeley National Laboratory has been involved in assessing and comparing existing systems, and designing an optimum system for UXO detection. A prototype of a new electromagnetic system will be ...
متن کاملGeological noise removal in geophysical magnetic survey to detect unexploded ordnance based on image filtering
This paper describes the application of three straightforward image-based filtering methods to remove the geological noise effect which masks unexploded ordnances (UXOs) magnetic signals in geophysical surveys. Three image filters comprising of mean, median and Wiener are used to enhance the location of probable UXOs when they are embedded in a dominant background geological noise. The study ar...
