Abstract :
Aiming at the difficulty on echo sampling when GPR is used for sub-bottom survey, equivalent time sampling is adopted to design the echo signal collecting system. Meanwhile, a new type of step system is presented which is based on cascaded AD9500. The step system can not only realize high resolution detection, but also give consideration to samples and sampling interval selectable. The experiment results indicate that the new type circuit is stable.
