Matched Field Processing (MFP) is the process of cross-correlation of a measured field with a modeled, predicted or replica field to determine a set of input parameters that yield the highest correlation. Typically, input parameters into a selected sound propagation model would include candidate range, bearing and depth of a source relative to the receiving array. The sound propagation model might be defined by environmental data such as sound speed profiles, bottom and surface conditions, tides, and composition of the water. The matched field processing would be employed to determine the location of the source the exact relative range, bearing and depth of the source. This book is for scientists and engineers who are familiarizing themselves with MFP and those in need detailed information about the process. The first two chapters address a brief history of MFP and discuss other types of processors used in underwater acoustics. The third chapter discusses where errors in MFP solutions occur due to errors in the propagation model. Chapter 4 gives the reader a familiarity of how linear and minimum variance processors perform under a wide range of conditions. And the last chapter addresses broadband processing, source movement and multiple sources.
