Abstract
Methods and apparatus are provided for determining the general direction of the origin of a projectile. At least one sensor, having at least three spaced-apart transducers, each being capable of encountering a blast wave generated at an origin of and by a propellant for the projectile, is provided for generating a signal responsive thereto. From the signals, a time relation is measured between at least three transducers when the blast wave serially encounters each of the three transducers. From the time relations, at least one unit sighting vector from at least one sensor to the origin of the blast wave is determined so that the unit sighting vector points in the general direction of the origin of the projectile.
