ABSTRACT: A ground probing radar system comprising a plurality of antennas for transmitting. Where for each transmitting antenna, anassociated individual driver means selectively operable in response to an enabling signal unique to each antenna. Upon receiving a triggering signal, the driver means supplies to its associated antenna a single impulse of power to be radiated. Further providing that a means for supplying the trigger signal to each of the driver means only one at a time, thereby insuring that no two antennas are supplied power to be radiated at the same time.
