An array of compact, inexpensive radars has been developed that utilizes commercial Doppler radar transceivers and box horn array antennas operating in the near field. The 25 x 25 radar unit array acts as a set of vibrometers that detect the acoustic mechanical resonances of buried land mines by sensing the ground motion above them. Operating with the antenna apertures 35 cm above the ground, spatial resolution, grid spacing, and location accuracy are 10 cm. The outputs of each radar unit, voltages directly proportional to the amplitude of the ground vibration displacement, include in-phase and quadrature components that are digitized to 18 bits resolution. A portable PC based LabVIEW program serves as the data processor to provide 25 simultaneous DFT spectra that isolate the mine resonances. Tests showed that the radar derived spectra are clearly discernible but, to some extent, subject to fluctuations due to coherent scattering from features on rough ground surface. One partially successful attempt to ameliorate these fluctuations is discussed.
