Abstract:

The primary effort of this project has been to develop and evaluate passive sonar receiver structures that make use of knowledge of the environment and received signal characteristics to detect, localize and classify the passive source, particularly in shallow water. Several structures have been or are being investigated. In shallow water, passive sonar context, the characteristics of received signals are determined by the properties of the source and by propagation through the ocean. Our hypothesis is that knowledge of the environment can be used to estimate propagation effects, which then provide information about the source location. Because the ocean environment is dynamic and variable in time and space, a statistical approach is necessary.
