Abstract
In this paper, the sensitivity of matched field processing to sound‐speed profile mismatch will be examined (based upon archival profiles resulting in various degrees of mismatch). A 10‐Hz source is considered whose field is generated by a normal mode model and only the water‐borne energy is used, thereby eliminating issues relating to the estimation of bottom parameters. This paper will examine how array parameters, i.e., number of phones and array depth, affect range and depth localization for various degrees of mismatch. In particular, it will be seen where an array is most and least sensitive to sound‐speed mismatch as a function of depth from the surface and range from the source, and the degree to which range and depth resolution are possible under ideal, as well as under likely, mismatch conditions.Keywords
