Abstract
A ground penetration radar (GPR) antenna system is integrated into a digging machine such that the system is configured to remain operable under the same environmental conditions as the machine. The system includes a GPR antenna and an inertial measurement unit (IMU). The GPR antenna includes a rectangular hollow enclosure made of a conductive material defining a cavity therein and is affixed to a bucket of the digging machine. The IMU is mounted to the hollow enclosure and provides a space trajectory over time of the GPR antenna on the bucket as the digging machine is operated.
Claims11
A ground penetration radar (GPR) antenna system, integrated into a digging machine such that the system is configured to remain operable under the same environmental conditions as the machine, the system comprising:
- a GPR antenna comprising a rectangular hollow enclosure made of a conductive material defining a cavity therein, said GPR antenna being affixed to a bucket of said digging machine,
- wherein said antenna comprises:
- a bow tie shared slot in a first portion of the hollow enclosure, where in the bow tie shaped slot has a longitudinal axis and a transverse axis of symmetry;
- an elliptical conductor which tapers along a longitudinal axis of the conductor from a feed point of a port, wherein a projection of the conductor on the bow tie shaped slot overlaps said transverse axis of symmetry;
- and
- an inertial measurement unit (IMU), mounted to said hollow enclosure, to provide a space trajectory over time of said GPR antenna on said bucket as said digging machine is operated.
A method for a ground penetration radar (GPR) antenna which is integrated into a digging machine such that the antenna is configured to remain operable under the same environmental conditions as the machine, the method comprising:
- having a GPR antenna comprising a rectangular hollow enclosure made of a conductive material defining a cavity therein and an IMU mounted to said hollow enclosure;
- wherein said antenna comprises:
- a bow tie shaped slot in a first portion of the hollow enclosure, where in the bow tie shaped slot has a longitudinal axis and a transverse axis of symmetry;
- an elliptical conductor which tapers along a longitudinal axis of the conductor from a feed point of a port, where a projection of the conductor on the bow tie shaped slot overlaps said transverse axis of symmetry;
- affixing said antenna and said IMU to a bucket of said digging machine;
- and said IMU providing a space trajectory over time of said GPR antenna on said bucket as said digging machine is operated.
