During the upcoming exercise, ZRay will carry a 27-element hydrophone array along
with its associated real-time detection, classification, and localization hardware and
software to perform real-time marine mammal monitoring. The CAD/CAM drawing of
ZRay in Fig. 2 shows the locations of the various passive acoustic sensor systems that can
be installed in the glider. Inside a sonar dome all along the wing’s leading edge is a 27-
channel hydrophone array with 15 kHz per channel bandwidth.
