Claim One:
1. A method for identifying a muzzle blast within a signal generated by an array of acoustic sensors forming an antenna, comprising: defining, by a processor, a width for a time window corresponding to a time required for the muzzle blast to traverse the array of acoustic sensors; detecting, by the processor, a shockwave within the generated signal; after detecting the shockwave, measuring, by the processor, total energy of the generated signal in a series of consecutive time windows as a function of time and as a function of the number of acoustic sensors that generated the signal, wherein each time window has the defined width; identifying, by the processor, one of the consecutive time windows having a maximum measured total energy relative to each of the remainder of the consecutive time windows; and associating, by the processor, the identified time window as corresponding to the muzzle blast.
