Abstract

This paper presents wide bandwidth, time decay signatures from recent unexploded ordnance (UXO) field experiment at a US Government UXO test site. While current technologies have shown the ability to detect buried metal objects, they tend to fail in discriminating the UXOs from metal objects that pose no risk. Metal target time decay measurements have been shown to be an excellent method for target classification and identification. The present paper addresses the research community's need for accurate, wide-bandwidth UXO target signatures. Metal target signatures for a number of important UXO targets are presented in the paper for both vertical and horizontal magnetic field excitation. Target time decay signatures from about 30 microseconds to 8 milliseconds are presented. Target signatures are also characterized using a non-linear parameterization scheme in an effort to develop a compact target signature library.
