Abstract:
The potential utility of biological sounds is examined from a sonar system perspective. Evaluation of the temporal, spatial, and spectral properties of these sounds from a system designer’s view can provide significant insight as to their possible function. The broadband sonar equations for both passive and active operations are used to evaluate this functionality with special attention paid to issues of shallow water propagation as well as those sound properties that most affect signal processing; time-bandwidth product, spatial and temporal resolving characteristics, and signal repetition rate. Specific examples are used to illustrate these findings, including blue and fin whale calls recorded off the coast of Southern California, bowhead whale calls from the spring migration off the coast of Barrow, Alaska, and humpback whale sounds recorded off the island of Hawaii. The use of a systems approach to evaluating biological sounds can also provide insight into several related areas of recent interest: (1) the effects biological sounds may have on man-made systems, (2) the effect man-made sounds may have on the ability of animals to communicate as well as acoustically sense their environment, and (3) designing underwater experiments to evaluate these issues.
