Abstract
A radar array comprising a panel, the panel comprising a top side and a bottom side; a plurality of high-frequency antennas coupled into a high-frequency array coupled to the panel; at least one low-frequency resistive vee dipole transmitting antenna; and at least one low-frequency resistive vee dipole receiving antenna, wherein the at least one low-frequency resistive vee dipole transmitting antenna and the at least one low-frequency resistive vee dipole receiving antenna are coupled into a low-frequency array.
Claims20
A method for detecting objects buried beneath a surface of a medium comprising:
- drawing a high-frequency array and a low frequency array across the surface, the high-frequency array comprising a plurality of high frequency antennas, the low frequency array comprising at least one-low frequency resistive vee dipole transmittal antenna and at least one low-frequency resistive vee dipole receiving antenna, wherein the at least one low-frequency resistive vee dipole transmitting antenna is configured to transmit electromagnetic waves in a direction orthogonal to electromagnetic waves transmitted by at least one of the high-frequency antennas;
- transmitting a plurality of high-frequency pulses of electromagnetic radiation with the high-frequency array;
- transmitting a plurality of low-frequency pulses of electromagnetic radiation with the low-frequency array;
- receiving the plurality of high-frequency pulses with the high-frequency array after interaction with the medium;
- receiving the plurality of low-frequency pulses with the low-frequency array after interaction with the medium;
- processing the plurality of high-frequency pulses;
- and
- processing the plurality of low-frequency pulses.
