| Abstract: | D seismic modeling experiment system mainly includes 3D auto control scanning, high speed sampling, ultrasonic pulse or varying frequency signal emitting ,etc., among which 3D auto control scanning and high speed sampling are the most important parts. This paper studies these two aspects in detail. Frequency changing and equivalent sampling were applied to solve the running accuracy of the scanning system and the problem of very high speed sampling. Equivalent sampling technique can also be applied to the acquisition of Radar and Sonar signals. |
