METHOD AND APPARATUS FOR ACOUSTIC DETECTION OF MINES AND OTHER BURIED MAN-MADE OBJECTS

摘要

An apparatus for remotely detecting land mines in compliant housings buried underground comprising: signal generator means for generating a probe signal having a first and a second frequency; source means for outputting the probe signal; receiver means for receiving a nonlinear frequency response vibration signal having a third frequency caused by the probe signal vibrating boundaries of a compliant object against a surrounding medium wherein the vibration signal is only generated when the probe signal impacts the compliant object, and processing means for processing the vibration signal.
