Uniformly-Sensitive Line Hydrophones.
Abstract
A uniformly-sensitive capacitive line hydrophone, dubbed WHOLINE, used as a towed broadband line hydrophone for seismic reflection profiling has produced significant increase in the signal-to-noise ratio. When used in a broadband noise field (less than 10 to several kHz) to detect signals that both approach the array at near normal incidence and are also broadband, the directivity of a long continuous line offers a specific advantage over that of an equal length linear array of openly spaced discrete sensors. Discrete arrays in such a sound field develop side lobes of full sensitivity at a number of frequencies at various angles to the array depending on the element spacing. In contrast, the side lobes characteristic of a continuous line are each successively reduced.
