Fig. 1. The experimental set up consists of a linear array of three hydrophones (A,
B, C) suspended between a buoy and a lead weight. The distance between the
hydrophones is 4 m, and the first hydrophone is at a depth of 4 m. Theclicking
animal is localized from the time- of-arrival differences
(t1, t2) of the same signal at the
three receivers. The rotationally symmetric position of the sound source
S(x,y) is given by the interception of the two hyperboloid surfaces
(H1, H2). Analogue signals are amplified and band-pass filtered in the
conditioning box before digitisation in the Wavebook 512, writing to the
memory of a laptop.
