Abstract
An adaptive gain transient electromagnetic receiving system based on exponential prediction and a method thereof are provided. The system includes a signal input unit, an amplification unit, a gain control unit, and a dual channel signal acquisition card. The signal input unit includes a receiving coil and a low-pass filter, and the amplification unit is a voltage controlled amplifier; the low-pass filter pre-processes the output signal of the receiving coil and divides the output signal into two signals. One is passed through a gain control unit, and the other enters into a voltage controlled amplifier. The A/D converter of the gain control unit converts the analog signal output by the low-pass filter into a digital signal, the FPGA module calculates the gain voltage, and the dual channel signal acquisition card collects the amplified signal and gain voltage simultaneously, which enhances the signal detection capability in deep regions.
