  • Wake and sub-sonic blast gunshot detection
    Patent number: 11519696
    Abstract: Trajectory estimate for a sub-sonic projectile can be derived from sampling a wake contribution of an acoustic signal detected at a multi-detector array. The wake contribution is sampled, in time, and the samples are processed to determine a bearing estimate for the projectile from which the acoustic wake derives.
    Type: Grant

    Date of Patent: December 6, 2022

  • Wake and shockwave gunshot detection
    Patent number: 11294022
    Abstract: Detection of a trajectory of a supersonic projectile is carried out derived from a plurality of acoustic detection signals. From these acoustic detection signals, two or more shockwave-derived trajectory estimates can be derived. Further, a wake derived trajectory bearing estimate can be derived, from which disambiguation of the shockwave-derived trajectory estimates can be effected.

  • Acoustic detector
    Patent number: 10274347
    Abstract: An acoustic detector provides a planar arrangement of microphones. A windshield is arranged over the microphones, with a view to reducing the impact of environmental effects. A void is therefore defined over the microphones, and the interior surface of the windshield, which defines the void, is shaped suitably to reduce the potential for acoustic waves propagating within the void to reflect back onto the microphones.
