Abstract:
An apparatus for identifying a buried object using array-based ground penetrating radar having a control device, a plurality of transmit antennas, and a plurality of receive antennas, said control device receiving a transmit timing input signal and a receive timing input signal, said apparatus comprising:a first delay circuit receiving the transmit timing input signal and generating a number of intermediate transmit timing signals delayed with respect to each other by a delay time; transmit output switch circuit to select either the transmit timing input signal or a corresponding one of the intermediate transmit timing signals as a corresponding output transmit timing signal; a second delay circuit receiving the receive timing input signal and generating a number of intermediate receive timing signals delayed with respect to each other by the delay time; a shift-delay circuit coupled to the second delay circuit and the receive timing input signal to add the delay time to the intermediate receive timing signals; and receive output switch circuit to select either the receive timing input signal or a corresponding one of the intermediate receive timing signals as a corresponding output receive timing signal.
