Abstract: For scoring of simulated firing of a weapon, having flatwise-angularly sweeping beams of radiation, emitted at the weapon location during a period beginning at or about the instant of simulated firing are used for measuring the position of a target retroreflector in range and in functions of azimuth and elevation. During the same period a calculation is made of the instantaneous positions in range, and in functions of azimuth and elevation, of an imaginary projectile fired from the weapon at the firing instant under conditions then existing, and the relationship is ascertained between the imaginary projectile and each beam in its angular position at interception by the retroreflector. At a scoring instant, when weapon-to-reflector distance equals weapon-to-projectile distance, or when the projectile is at a predetermined elevation relative to the reflector, scoring is based on the relationship of projectile to angular beam position at that instant.
