ABSTRACT:
The current invention discloses a construction of a hydrophone body and hydrophone sensors which provides a significantly enhanced wide band frequency sensor capability within the construction of a sensor array towed in a cable. This construction extends a tuned resonator or sensor along the hydrophone body and into an adjacent section of interconnecting cable. This elongated sensor, in the form of a tubular sensor, provides an enhanced, very low frequency sensing capability within the overall hydrophone array, supplementing the frequency range of the encased hydrophone sensor.
