Cross Correlation Loss Due to Bottom Reflection.

Abstract

The bottom is considered to act as a linear filter. For specific conditions, the literature shows that this filter has a phase shift that is constant for all frequencies and an exponential attenuation with frequency. A random function that has a flat finite bandwidth is considered. The problem is to obtain the cross correlation for the direct with the bottom reflected version of this random function. A mathematical equation is derived. This equation is now being programmed. Curves are presented for the special case of phase shift only. Curves for the more general case will be presented at a later date.
