A method for firing a computerized radar weapon system upon a fast target to reduce errors in aim caused by aim-biasing factors that vary in time and space includes computing a point along an extrapolated target track ahead of the target at which to stage an interception. A spotting round is fired at the point to zero-in just before the interception and then a correctly-aimed intercept round is fired at the point in time to make the interception. Additional interceptions may be staged at backup intercept points to guard against a miss, a burst of spotting rounds may be fired at an intercept point to average out perturbations in the trajectory of the projectile from each one of the rounds, and conventional monopulse radar methods of aim bias measurement may be employed to detect projectile miss information.

A method for firing a computerized radar weapon system upon a fast target, which comprises; computing an intercept point ahead of the target at which to stage an interception; computing an extrapolated target track for the target along which to stage the interception; computing an intercept point on the extrapolated track that is ahead of the target by a distance corresponding to the sum of the time required to aim and fire a spotting round at the intercept point, the time required for a projectile from the spotting round to reach the intercept point after being fired, the time required to measure and analyze the aim of the spotting round, the time required to fire a correctly-aimed intercept round, and the time required for a projectile from the intercept round to reach the intercept point; zeroing in on the intercept point with a spotting round before the interception; and then firing a correctly-aimed round at the point in time to make the interception; thereby reducing errors in aim caused by aim-biasing factors that vary in time and space.
