Abstract
This report documents the work done to support the development and evaluation of two transient localization algorithms. It is intended to use these algorithms to recommend methods of localizing marine mammal vocalizations. Two algorithms and prototype software, provided by Dr. Joe Maksym, Defence R&D Canada (DRDC) – Atlantic, were integrated into the Software Tools for Analysis and Research (STAR) software suite. One algorithm uses transient arrival angle (bearing fixing) and the other uses time difference of arrival measurements (hyperbolic fixing). Supporting work was done to enhance the existing power spectra image application to support detection and processing of transient events using a semi-automated method, and to enhance databases and the program framework to support transient logging. This work was built on previous work that used multistatic main blast and echo data to perform constant travel time (elliptical) fixing. Only preliminary processing was conducted on real data to confirm the algorithms function on a realistic dataset. More extensive testing was performed using synthetic data. All data processing was performed using the Signal Processing Packages (SPPACS) software suite.
