Abstract
A multi-modal ground penetrating radar includes a radar set configured to launch predistorted double-sideband (DSB) suppressed-carrier modulated continuous waves (CW) to illuminate and penetrate a ground surface. A variable frequency modulator is connected to modulate a continuous wave (CW) carrier frequency generator within the radar set to yield a double-sideband suppressed carrier output. A lateral single-file array of antennas is configured to be flown closely over the surface of the ground. A multiplexing switch is connected to the array of antennas and configured to selectively switch individual ones of the antennas to the radar set. Any early arriving signals returned from geologic clutter and surface reflections are suppressed in synchronous detection in relation to signals received by the array of antennas from less shallow depths. Interesting objects below the ground surface are detected and located by the late arriving signal reflections.
