摘要

A system for estimating a shooter range by detecting shock wave and muzzle blast, comprises a plurality of spaced acoustic sensors forming an antenna for measuring shockwave-only signals; and means for measuring a muzzle blast signal at the plurality of acoustic sensors. From the measured shock wave and muzzle blast signals an initial estimate of the shooter range is determined. Then assuming an initial bullet velocity and a bullet drag coefficient, an instantaneous bullet velocity along a bullet trajectory is iteratively computed to obtain an updated shooter range.
