Systems and methods for locating the shooter of supersonic projectiles are described. The system uses at least five, preferably seven, spaced acoustic sensors. Sensor signals are detected for shockwaves and muzzle blast, wherein muzzle blast detection can be either incomplete coming from less than 4 sensor channels, or inconclusive due to lack of signal strength. Shooter range can be determined by an iterative computation and/or a genetic algorithm by minimizing a cost function that includes timing information from both shockwave and muzzle signal channe...
What is claimed is: 1. A method for determining an unambiguous projectile trajectory using an array of spaced acoustic sensors when a shockwave associated with a projectile is detected by at least five of the sensors but a muzzle blast associated with the projectile is detected by fewer than four of the sensors, comprising: obtaining four or more shockwave TDOA measurements from the sensors detecting the shockwave, wherein the shockwave TDOA measurements are insufficient to compute the unambiguous projectile trajectory; obtaining fewer than three muzzle...
