Abstract:
1. A multi-modal ground penetrating radar (MMGPR), comprising: 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 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 configured to be flown closely over the surface of the ground; and a multiplexing switch connected to the array of antennas and configured to selectively switch individual ones of said antennas to the radar set; wherein, 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; and wherein, objects below the ground surface are detected and located by said late arriving signal reflections.
