Claim One:
1. A gunshot location system comprising a collection of acoustic sensors, a computer for computing gunshot locations using information communicated from the acoustic sensors, and communication links connecting the acoustic sensors to the computer, wherein the collection of acoustic sensors comprises a first acoustic sensor and a second acoustic sensor, wherein the first acoustic sensor communicates to the computer time-of-arrival information derived from acoustic impulses sensed at the first acoustic sensor and angle-of-arrival information derived from the acoustic impulses sensed at the first acoustic sensor, wherein the second acoustic sensor communicates to the computer time-of-arrival information derived from acoustic impulses sensed at the second acoustic sensor; and wherein the computer for computing gunshot locations computes a hyperbola from the time-of-arrival information communicated from the first and second acoustic sensors, computes an angular beam from the angle-of-arrival information communicated from the first acoustic sensor, and computes a candidate gunshot location from an intersection of the hyperbola and the angular beam.
