Abstract

A Monte Carlo model has been used to determine a set of point spread functions and modulation transfer functions for underwater imaging in different environments. The results have been used to examine the validity of a linear approximation theory. The conclusions are that the linear approximation theory works to some extent, however, a slight modification can be used in order to obtain good quantitative agreement. In particular, an empirical effective beam attenuation function is used for each different environment in order to insure the accuracy of the linear treatment.
