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. [This work was supported by the
