Networked Acoustic Sensor Array's Performance During 2004 Horizontal Fusion - Warrior's Edge Demonstration

Abstract : As the Army transforms to the Future Force, particular attention must be paid to operations in Complex and Urban Terrain. because our adversaries realize that we don't have battlefield dominance in the urban environment, and because population growth and migration to urban environments is still on the increase, our adversaries will continue to draw us into operations in the urban environment. The Army Research Laboratory (ARL) is developing technology to equip our soldiers for the urban operations of the future. Sophisticated small robotic platforms with diverse sensor suites will be an integral part of the Future Force, and must be able to collaborate not only amongst themselves but also with their manned partners. ARL has developed a Reconnaissance, Surveillance, and Target Acquisition (RSTA) sensor payload for integration onto small robotic vehicles (Packbots), larger robotic scout vehicles (M-Gators), manned soldier transports (ATVs), and on a tethered aerial platform (aerostat). The RSTA sensor payload is equipped with an acoustic array that will detect and localize on an impulsive noise event, such as a sniper's weapon firing. Additionally, the robot sensor head is equipped with visible and thermal camera for operations both day and night. The Packbot can be deployed from the soldier's ATV to enhance their situational awareness in the urban environment, while keeping them out of harms way. The information from one Packbot can then be fused with other sensors as part of a sensor network. Sensor equipped mobile platforms provide an awesome capability to the future dismounted infantry soldier during warfighting and peacekeeping operations in complex and urban terrain by enhancing their situational awareness and improving their survivability. ARL demonstrated networked acoustic detection and localization of mortar, sniper fire, gunfight, and vehicle tracking at the August 11, 2004 Horizontal Fusion - Warrior's Edge (WE) demonstration at the at Fort Benning, Ge7
