Ground probing radar with multiple antenna capability
TLDR
In this paper, a ground probing radar system comprising a plurality of antennas for transmitting is considered, where for each transmitting antenna, an associated individual driver means selectively operable in response to an enabling signal unique to each antenna.Abstract:
A ground probing radar system comprising a plurality of antennas for transmitting. Where for each transmitting antenna, an associated 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.read more

Antenna coupling component measurement tool having rotating antenna configuration
Michael S. Bittar,Guoyu Hu +1 more
TL;DR: In this paper, an antenna configuration with at most two transmitter or receiver antenna orientations that rotate relative to the borehole is described, and the measurements made by this reduced-complexity antenna configuration enable the determination of at least seven components of a coupling matrix, which may be determined using a linear system of equations that express the azimuthal dependence of the measurements.
Patent
Ground penetrating radar system
TL;DR: In this paper, a ground penetrating radar system includes a cart configured to be movable along the ground and a computer is mechanically coupled to the cart, which is configured to trigger the radar electronics module when the computer detects that the cart has moved a predefined distance.
