Abstract
Data fusion from two separate and orthogonal mine detection sensors developed independently by the University of Mississippi and Planning Systems Inc. has been performed. The University of Mississippi's acoustic/seismic coupling detection is based on the measurement of ground surface vibration velocity by means of acoustic excitation and a laser Doppler vibrometer. Differences in absolute surface vibration velocity, caused by the present of buried mines, are used to infer the presence of buried land mines. Planning Systems Inc. uses ground-penetrating, synthetic- aperture radar to detect subsurface electromagnetic anomalies. Detection with the GPSAR sensor is based on differences in the dielectric constant of the ground medium and that of a buried land mine. The spatial resolutions of the two measurements are similar and the two sensors measure completely different physical properties. Dat form each system are described in detail and independent examples of performance are presented. A common geo-spatial grid is defined for both sensor systems given their respective resolving capability. Methods of simultaneous display are presented and situations in which the two systems are complementary are identified.
