Abstract

The invention provides a ground penetrating radar transmitting voltage dynamic adjusting system which adopts a transmitting antenna subsystem and a receiving antenna subsystem which are arranged in a split mode. Through the FPGA chip, the digital potentiometer is adjusted to reduce the level of the high-voltage power supply under the condition that the range of the analog-to-digital converter is full and / or the direct wave is saturated, and the digital potentiometer is adjusted to increase the level of the high-voltage power supply under the condition that the range of the analog-to-digital converter is not full and / or the direct wave is unsaturated, so that the ground penetrating radar can better adapt to different geological conditions. The signal-to-noise ratio of the signal is improved, the detection resolution is further improved, different detection tasks can be quickly responded, and hardware replacement or complex setting does not need to be carried out.
