Abstract
The United States Submarine Force currently conducts lengthy pre‐ and post‐repair evaluation of submarine hull‐mounted arrays using extensive, highly specialized external equipment and facilities. A methodology using transmission of acoustic energy between array elements employing portable test equipment controlled by a desktop computer has been developed that allows very rapid measurement of voltage and current parameters required for calculating sensitivities of acoustic transducers in situ. The method is an adaptation of one described by Van Buren [NRL Memorandum Report 5642, July 1985]. The method has been successfully applied to the determination of relative sensitivities for staves of DT‐276 hydrophones in submarine hull‐mounted arrays. Also, the method has been successfully adapted to detect the improper wiring of hydrophones in a stave of the array. The method is valuable since all measurements are performed from onboard the submarine. An outline of the procedures and examples of results will be presented.
