Abstract
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.
