An Analytic Model of Cross-correlation in a Bottom Bounce Environment
Abstract
Intersensor cross-correlation can be significantly affected by acoustic multipath. An analytic model has been developed to simulate band-1imited cross-correlation for an environment in which the propagation is represented as four first-order bottom bounce rays. The "four path" model is intended to be an aid in understanding how cross-correlation is affected by bottom bounce conditions. This memorandum describes the geometry and assumptions of the analytic four path model, presents the supporting mathematics, computes normalized cross-correlations and compares computed normalized cross-correlations with correlations generated by the Generic Sonar Model. The rms error between the two models was found to be less than 0.1 percent for the three test cases examined.
