Vector Sensor Array for Torpedo Defense

For the problem of torpedo detection, classification and localization, acoustic vector sensors provide the capability for significant performance improvement. In particular, acoustic vector sensors are inherently directional. Vector sensors are generally defined as co-located pressure sensors and directional displacement, velocity, or acceleration sensors (all are generally referred to as velocity sensors). Moreover, vector sensors can provide unambiguous bearing in a linear array configuration. The ability to provide unambiguous bearing localization is important for torpedo defense. 3 Phoenix proposes novel signal processing technology for the suppression of interference and noise on a linear array of vector sensors. It is expected that the technology developed under this STTR will provide a quantum improvement in torpedo detection and localization.
