 | Feature extraction methods based on the discrete wavelet transform (DWT) and multiresolution analysis are used to develop a robust classification algorithm that reliably discriminates between launch and impact artillery and/or mortar events via acoustic signals produced during detonation. Distinct characteristics are found within the acoustic signatures since impact events emphasize concussive and shrapnel effects, while launch events are similar to explosions, designed to expel and propel artillery round from a ... |

| The Army is currently developing acoustic sensor systems that will provide extended range surveillance, detection, and identification for force protection and tactical security. A network of such sensors remotely deployed in conjunction with a central processing node (or gateway) will provide early warning and assessment of enemy threats, near real-time situational awareness to commanders, and may reduce potential hazards to the soldier. In contrast, the current detection of chemical/biological (CB) ... |

| The Catadioptric Omni-Directional System was developed by the U.S. Army Armament Research, Development and Engineering Center (ARDEC) Acoustic and Network Sensors Office, Picatinny Arsenal, New Jersey to demonstrate existing technologies that could increase situational awareness for the M1A2 Abrams' crew. The project required a rapid and easily incorporated solution that could attach to the tank without permanent modification and at low cost. On 23 February 2005, the completed system was ... |
