abstract

Acoustic-seismic coupling mine detection offers an alternative approach to distinguishing mines from clutter. The approach is based on the principle that an area with a buried object shows a different response to acoustic excitation from that of the surrounding soil. Prior research shows that the response in the low frequency range can be captured using simple physically based models under certain conditions. According to the models, areas with buried mines exhibit natural frequencies that can be determined from mine types and buried depths. In this paper, we argue that not only are the natural frequencies useful for the purpose of mine detection, but the locations of the transmission zeros are important as well. Under certain conditions, the locations of the transmission zeros are also less sensitive to changes in physical properties of mines. We take advantage of this characteristic and offer a method to improve signal-to-clutter ratio for the purpose of automatic mine detection.
