An acoustic cannon has a plurality of acoustic sources with output ends symmetrically arranged in a planar array about a central point. Pressure pulses are generated in each acoustic source at substantially the same time. The pressure pulses exit the output ends as sonic pulses. Interaction of the sonic pulses generates a Mach disk, a non-linear shock wave that travels along an axis perpendicular to the planar array with limited radial diffusion. The Mach disk retains the intensity of the sonic pulses for a time and a distance significantly longer than that achievable from a single sonic source. The acoustic cannon is useful as a non-lethal weapon to disperse crowds or disable a hostile target.

[ We claim:] [1.] An acoustic cannon, comprising:a plurality of acoustic sources each having an input end and an output end with an interior bore disposed therebetween, each said input end receiving a plurality of discrete sonic pulses and each said output end emitting a sonic output in the form of discrete sonic pulses;a sonic pulse generator coupled to each said input end; anda timing mechanism coupled to said sonic pulse generator such that each one of said discrete sonic pulses is received by each one of said input ends at substantially the same time and is of substantially the same frequency and duration when emitted from each one of said output ends whereby a plurality of said sonic outputs interact to generate a shock-driven output pulse.
