Abstract
As a high-tech method of electrical prospecting, borehole-ground controlled source electromagnetic imaging is aimed to enhance the detection depth and increase resolution appropriately. It requires the signal recording instrument to be a ground and underground (pit, wells) quasi-three-dimensional receiver. To record signals of the natural field and controlled source from 0.1Hz to 20KHz in N * 10nV - N * 100mV amplitude range, we used a series of new technology, such as ARM + LINUX embedded, low-noise high-precision, GPS synchronization and low drift, low-power, NET, high-capacity storage, to develop a borehole-ground controlled source electromagnetic recorder with large dynamic range of broadband. Field survey data indicate that this signal recorder can work in a normal and stable manner, and all expected technical indexes have been largely reached.
