Progress in Metal-Detection Techniques for Detecting and Identifying Landmines and Unexploded Ordnance

摘要

This report assesses the current state of research in the use of metal detectors to detect and identify unexploded ordnance and landmines. This report recommends that new time-domain, frequency-domain, and combined time/ frequency-domain detectors be theoretically designed, constructed, and tested against small targets and clutter roughly the size of the U.S. M-14 mine (< 5 cm diameter, < 5 g metal). The report further recommends that the design and test information be made publicly available to enable future design and analyses improvements. It is also recommended that advanced signal-processing techniques be used to complete the definition of optimized electromagnetic induction performance against small targets.
