| Abstract: |
RobTre Research proposes to develop an algorithm that reduces severity and duration of blurred focus and the associated reduction in visibility and detectability ranges caused by tow ship maneuvering. It also improves left-right disambiguation during straight line towing. The proposed approach is a robust automated real-time array shape estimation algorithm that uses acoustic data inversion in combination with available information from shape measurement instrumentation such as heading sensors. The algorithm integrates as a natural augmentation of existing linear space-time correlation processors. |
| Benefits: |
The proposed research and development effort will improve active and passive towed array receiver performance as well as the performance of any system using a spatially dynamic sensor array for detection and localization of sources of propagating waves. |
