Vibroseis data acquisition, compactions, and enhancement

Vibrosais data collection is different from traditional seismic data acquisition in the fact that some sort of a continuous sweep signal is used as a source instead of an impulse. This type of source has many advantages over its predecessors and is fast gaining popularity. This thesis presents the results of simulating Vibroseis data acquisition in the Allied Geophysical Laboratories and the effects of various parameters on the final output. The results of data compaction using linear and pseudo-random sweeps are documented. The design and results of building a programmable signal generator are shown. This generator is used to enhance the quality of the data collected by driving the source with a modulated sweep. The data collected using this method are compared with the previous results.
