Abstract

The detection and localization of small fire arms is envisaged by use of acoustic devices. This paper describes the capability to detect and localize snipers in open field and in urban conditions. This work was performed by ISL and DGA during various national and NATO trials. During recent military conflicts, as well as for security interventions, the urban zone has taken a prominent place. Experimental results measured in free-field conditions, compared with those measured in a village used for military training, show that the streets and houses can generate many reflections of the original gunshot, requiring new signal processing techniques to separate each contribution. For this purpose a specific numerical model has been developed. A few examples of experimental and numerical results obtained for the validation of this methodology will be presented.
