Abstract:

This thesis examines the range error propagation and uncertainties associated with bistatic sonar operations. An equation for determining range to the target from the receiver is explored for feasibility of practical applications. This particular equation does not require the separation distance between the source and receiver however, it does require an assumption of the mean sound speed over the two paths of the signal even though it could change drastically over a few miles. This thesis explores the contribution of eccentricity on the bistatic ellipse and the associated error. Examples demonstrate these effects by comparing cases of unequal mean sound speeds over the different paths at different values of eccentricity.
