Patent ID: 7173560

Claim:
A forwarding looking ground penetrating mine detection apparatus, comprising: a movable vehicle; a radiation source comprising dual transmitting antennas mounted on said movable vehicle for irradiating a sample of ground suspected of containing at least one mine with a plurality of frequency swept ground penetrating radar signals, each of said radar signals having a discrete frequency, the discrete frequencies being evenly spaced over a predetermined frequency range; and a detector comprising a plurality of evenly spaced-apart receiving antennas mounted on said movable vehicle for receiving target signals backscattered from said ground responsive to said radar signal, said detector including a time-frequency analyzer, said time-frequency analyzer transforming said target signals into a time-frequency image representation (TFR); wherein said transmitting antennas operate sequentially in irradiating the sample, and wherein said receiving antennas operate simultaneously in receiving the target signals.
