The Naval Research Laboratory and Maryland Advanced Development Laboratory MADL have worked on the detection of small arms gunfire using land-based systems and on detection of larger ordnance using airborne-based systems. The primary detection mechanism is the sensing of the muzzle flash in the Mid-Wave Infrared 3-5 um band. Improvements in algorithms and sensors have enabled real-time detection from wide angle cameras without loss of range performance. Shooting events are detected beyond the effective firing ranges of the weapons and with low false alarms. Post-detection imaging of shooterssnipers has been validated for day and night operations. The utility of these sensors is amplified by linking the data to other friendly forces. Network hardware and data protocols have been developed that permit the transmission of the sensor data at both local levels and to remote command stations in real time. This research in ordnance detection is being extended with the development of Gunfire Detection and Location units mounted on HMMWVs. This effort will provide these Operational Experimentation Articles for small-arms muzzle blast detection together with EOIRAcoustic adjuncts to enable warfighters to rapidly validate gunfire events and to properly engage enemy shooters. Day and night cameras as well as lasers are mounted on a commanded gimbal. This configuration provides 24-hour situational awareness to the operator when not engaged in gunfire detection and location. The operational experimentation will aid in the development of new CONOPS concept of operations for the warfighter. The systems capability to link hostile positions to other sensors andor weapons enables a very rapid response to the counter the enemy. Further work in airborne detection and advanced systems is planned.
