Description:

This is a continuation of an on-going investigation in conjunction with Thomson Marconi Sonar Pty. Ltd., Pooraka. Vibration of a towed underwater sonar array and propagation of acoustic waves in its internal fluid produce pressures on the hydrophones in the array. These pressures appear as noise in the acoustic signals the array is designed to detect. Measurements are to be made of the characteristics of the vibrational waves propagating in the jacket and internal fluid on a 10 meter long module of a towed array.
