GUNSHOT DETECTION SYSTEM AND METHOD

摘要

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.

主权项

1. A method for use in detecting and locating a muzzle flash event, the method comprising imaging electromagnetic radiation by an imager comprising a non cryogenically cooled Photo Detector Array (PDA) sensitive in at least a portion of a SWIR spectrum, wherein said electromagnetic radiation propagating towards the PDA undergoes filtering for selectively passing towards the PDA the electromagnetic radiation of one or more spectral ranges of relatively low transmission in atmosphere of said at least portion of the SWIR spectrum.
