Array Processing That Uses a Normal-Mode Model for Signal Representation

Abstract

A signal processing procedure is designed for a hypothetical low frequency sonar array. The design process is based upon the normal mode expansion of the signal field. Unusual problems associated with this expansion are discussed and some useful simplifications are found. Basic array processing formulations are redeveloped to accommodate the possibility of a signal field which is a superposition of known wave fronts.
