Locating a shooter from the first shot via mobile phone

摘要

Militaries have worked for decades to develop technologies that simultaneously protect infantry soldiers' hearing and aid in battlefield communication. However, these advanced Tactical Communication and Protective Systems (TCAPS) - earmuffs or earplugs with built-in microphones allowing active hearing protection - don't help if a soldier takes them off to assess the location of incoming gunfire. Now a French researcher has developed a proof of concept that uses the microphones in a TCAPS system to capture a shooter's acoustic information and transmit this to a soldier's smartphone to display shooter location in real time.
