Description
A computer-efficient model of the underwater acoustic propagation m a
shallow, three-dimensional duct closed at one end has been developed using
the method of images. Presented in this research is the development of this
three-dimensional method of images analysis for a rectangular duct. Using
this analysis, a model of the impulse response of the acoustic channel is
constructed. Also presented in this work is the actual impulse response
collected during field experimentation in the south turning basin of Port
Everglades in Fort Lauderdale, Florida. The results demonstrate that the
impulse response is modeled with a relative echo magnitude error of 1.62 dB
at worst, and a relative echo location error varying between 0% and 4% when
averaged across multiple measurements and sensor locations.
