In previous work [Smith and Akundi, 2980(A) (1994)] analytic expressions for mismatch-induced range localization error and signal gain degradation for a linear correlator matched-field processor were obtained. Those results agreed with previously obtained results [Shang and Wang, 2285--2290 (1991)]. In this work the problems of mismatch-induced depth localization error and the source depth dependence of both range and depth localization errors are addressed. Computer simulations show that the analytic predictions obtained here are not perfect but are close enough to indicate that this line of research is on the right track.
