Range Error Estimates due to Depth and Bottom Slope

Abstract

Errors in range estimation by a single bottom bounce path are examined for several bottom geometries. The range error due to an incorrect water depth is examined, and it is shown that for horizontal bottom planes, the range error as a function of depth error is independent of the absolute water depth. Range errors associated with two bottom models with non-horizontal bounce point planes are examined. The range errors are studied as functions of depression angle, water depth, bottom slope, and cross slope angle. Computer programs have been written which calculate the range errors and the results are presented as contour plots. The results show the importance of accurate bathymetry for range estimation.
