False Indicators to Acoustic-To-Seismic Buried Landmine Detection

Abstract

The proliferation of relatively cheap landmines in many of the world's conflicts has led to a critical situation. Most methods of locating landmines trigger on too many false alarms must each be investigated before declaring an area to be clear of mines. This led to the need for an accurate means of detection coupled with a low false alarm rate. The University of Mississippi has developed an acoustic/seismic technique to meet this need. In 2002, the Office of Naval Research issued Grant N00014-02-1-0878 to conduct research to better understand the causes of false alarms using this method and to develop methods to significantly reduce them. This report discusses the significant research advances including a clearer understanding of the phenomenology underlying the technology, development of models, and signal processing techniques to reduce false alarms.
