Abstract
Disclosed are systems and methods that can be used to detect shooters. The systems and methods described herein use arrival times of a shockwave, produced by a shot, at a plurality of sensors to assign weights to each of the plurality of sensors, and determine a shot trajectory based on the assigned weights.
Claims10
A method for operating a multi-sensor shooter detection system, comprising
- providing a plurality of sensors,
- determining arrival times of a shockwave produced by a shot at each of the plurality of sensors,
- determining a time residual based at least in part on the arrival times,
- determining a contribution of each the arrival times to the time residual,
- assigning a weight to each of the plurality of sensors based on the contribution, and
- determining a shot trajectory based on the weight.
