GRAPHICAL DETERMINATION OF THE RESPONSE OF A SIMPLE LINE HYDROPHONE TO TWO SOURCES

Abstract

A graphical determination of the line hydrophone's response to two sources was made by vector addition of elemental contributions. The results were then applied to the specific cases of a 3-wavelength line in the p r e 5 en c e of (a) two equal-amplitude sources in phase and 180 degrees out of phase and (b) two sources in the amplitude ratio 1:2, in phase and 180 degrees out of phase. Plots were' made for source separations from 0 degrees to 50 degrees. It wu shown that at source separations smaller than a lobe width the hydrophone becomes susceptible to a pointing error such that the direction of maximum response may be outside the angle included by the sources.
