1. In a method of detecting muzzle blasts at a distance comprising the steps of generating an infrared image signal of a selected field of view and outputting said infrared image signal in frames as a live infrared video signal, spectrally filtering each frame of said live infrared video signal to pass only frequencies within a predetermined infrared frequency range, temporally filtering each frame of said live infrared video signal to only include events within a predetermined time period, spatially filtering each frame of said live video signal to pass only said video signals having a predetermined shape, and combining the results of the spectral, temporal and spatial filtering to determine the presence or absence of a muzzle blast within said field of view, determining the coordinates of position of any detected muzzle blast within said field of view.
