5203 |aThere is presently a need for clearing old army ranges of buried unexploded munitions (UXM). The present operation which relies on conventional metal detectors is very slow and expensive - mainly due to the inability of these detectors to provide any information as to the depth, size or nature (shrapnel or UXM) of detected objects. The paper discusses the research effort of the Mines and Range Clearance Group at DRES, towards conceiving and implementing intelligent detectors, which could provide ordnance depth, size and possibly identity. In particular, the analysis of magnetic anomaly and pulse eddy current signatures of typical ordnance are discussed. Signal processing problems specific to these applications are indicated and the viability of various feature selection, extraction and recognition schemes are discussed.
