Abstract:
1. A system for estimating a location of the source of a projectile, comprising: a radar system for transmitting a wave and detecting and providing an indication of a wave reflection from the projectile; an acoustic detection system for detecting and providing an indication of at least one sound associated with the projectile; and circuitry for estimating the location in response to the indication of a wave reflection and the indication of at least one sound; wherein the radar system comprises circuitry for transmitting the wave along a boresight line and further comprising circuitry for providing a set of boresight line-to-projectile distance angles, wherein each boresight line-to-projectile distance angle in the set comprises an angle between the boresight line and a range distance to the projectile at a respective time; wherein the projectile passes along a projectile path; and further comprising circuitry for providing a set of projectile path-to-radar location angles, wherein each projectile path-to-radar location angle in the set comprises an angle between the projectile path and a location of the radar system.
