ABSTRACT:
An improved hydrophone body, suitable for forming an array of towed hydrophone bodies or "fish", formed by placing an acoustic shield or scatterer in the nose and tail sections of the hydrophone body to reduce noise coupling from the cable into the hydrophone sensor. This resulting hydrophone has significantly reduced background noise interference.
