The ShotSpotter Gunshot Location System® has a flexible architecture that employs a wireless network of sensors mounted on buildings, vehicles, or soldiers. These distributed arrays with redundant acoustic paths combine audio time of arrival and/or angle of arrival from multiple sensors to calculate locations in challenging environments with obstructions or reflections. Muzzle and bullet sounds can be used depending on the proximity of the sensors to the bullet trajectory. Large array geometries allow not only close-range sniper detection but also wide-area situational awareness of enemy weapon activity. Examples of acoustic detections are presented in this paper using data from a combination of fixed and mobile sensors.
