Research Project

This project will attempt to extend the use of stepped frequency domain reflectometry (FDR) into seismic applications. Present vibration based seismic studies use a linearly increasing frequency or "chirp" that ranges from 10 Hz to 120 Hz. The new method can compensate for signal dispersion and coherent detection can eliminate harmonic components that originate from the vibrator. The new method is expected to provide longer range, improved resolution and better immunity to noise. In addition to reflection magnitude which is available from the present swept frequency method, the new technique is able to measure reflection angle which may assist in determining the type of subsurface discontinuity. Acquisition of data using the proposed stepped frequency method takes much longer than the swept frequency methods currently used and the project will investigate methods to minimize acquisition time.

    • Biography

    David Scharbach was born in Kamloops, British Columbia in 1977. In 1995, he began the pursuit of a degree in Pharmacy before he was bitten by the Engineering bug. Starting in 1997, he enrolled in the college of Engineering and received his Bachelors Degree in Electrical Engineering, with distinction, in May of 2001. David focused his engineering undergraduate studies on Instrumentation, Control and Communication systems. Shortly after graduating, David entered into private business with his father for period of two years. In the fall of 2003, David enrolled in the Graduate program of Electrical Engineering at the university of Saskatchewan where he is still currently working towards his M.Sc.
