Gunshot detection system and method

Abstract

A device and a method for use in detection of a muzzle flash event is described. The device can include a Photo Detector Array (PDA), sensitive in at least a portion of the NIR and SWIR spectrum, and a filter of electromagnetic radiation selectively passing in this portion a spectral range of low atmospheric transmission, the PDA has an integration time shorter than a duration of the muzzle flash event.

AI Technical Summary

Benefits of technology

The present invention provides an improved method for detecting high-speed light emission, including from firearms guns shots and muzzle flashes. This new technique allows for more accurate identification of these events.

Problems solved by technology

This patent discusses different ways to detect and locate weapon fired, particularly snipers. The technical problem addressed is finding effective and affordable methods without being obstructed by muzzle flash or excessive heat generated during combustion. Various techniques like muzzle flash detection through optical signals, analysis of shock waves created by the bursting of ammunition, and tracking of retro-reflected laser pulses have been developed but come with their own limitations and costs. Additionally, combining multiple detection methods could offer better results but requires further research and development.
