The present invention pertains to a software-defined, multi-frequency utility locating transmitter utilizing GaN-based switching technology for enhanced signal control and efficiency. The transmitter features a high-frequency H-bridge driving a low-impedance air-coil antenna to emit multi-frequency continuous waves. A control unit dynamically adjusts frequency, amplitude, and power based on real-time feedback, enabling signal correction and interference mitigation via real-time spectrum analysis by software means.

Software-defined GaN-based utility locator transmitter

A system for detecting underground utilities in a certain area, comprising one or more transmitters deployed to transmit electromagnetic signals in one or more frequency bands into the ground in a certain area, one or more electromagnetic sensors adapted to capture electromagnetic radiation emitted by one or more underground utilities in the certain area responsive to excitation by the electromagnetic signals transmitted by the transmitter(s), and one or more processors communicatively coupled to the electromagnetic sensor(s) and adapted to detect the underground utility(s) according to the electromagnetic radiation captured by the electromagnetic sensor(s). wherein the transmitter(s) are adapted to maintain a transmission power of the electromagnetic signals above a certain power threshold by adjusting an amplitude and/or a frequency of each electromagnetic signal to induce a current exceeding a certain current threshold through an antenna feed circuit to compensate for external impedance affecting the one or more transmitters.
