  • Counter target acquisition radar and acoustic adjunct for classification
    Patent number: 7952513
    Abstract: A system for classifying targets utilizes radar receptions and acoustic signatures of armament projectiles (e.g., bullets from celebratory rifle fire, mortars, cannon fire, artillery shells, or rockets, etc.) to associate ordinances with radar returns to better utilize a radar's resources to acquire and track targets of interest. In one embodiment of the invention the system for classifying targets comprises: a radar system for detecting targets based upon radar receptions; an acoustic system for detecting targets based upon acoustic receptions; and a means for classifying the acoustic receptions into target types; a means for computing range, bearing and time of incidence for the radar receptions and the acoustic receptions; a means for associating the radar receptions and the acoustic receptions according to the classification.
