Uniformly-Sensitive Line Hydrophones

Abstract

A uniformly-sensitive line hydrophone under development at the Woods Hole Oceanographic Institution has been used to receive broadband seismic reflection signals. The directivity characteristics of an adequately-long continuous line sensor used in a broadband sound field (less than 10 Hz to several kHz) are not easily obtained by arrays of discrete sensors. Discrete element arrays in a sound field of such wide frequency range inevitably develop side lobes of full sensitivity at a number of frequencies at various angles to the array. It is of particular utility that the side lobes of a continuous line hydrophone are each successively reduced. (Author)
