Title: Effect of Phase Errors on the Direction-Finding Precision of Hydrophone Arrays
Abstract: One limit to the precision of finding the direction of an underwater sound source with an electrically steered array is the phase error in each hydrophone output signal. A theoretical relation between the standard deviation of hydrophone phase error and the standard deviation of array direction-finding error is derived in this paper. Supporting experimental evidence is presented from measurements on two multielement, scanning-sonar-type, circular arrays.
