DTIC ADA028209: Mathematical Model for Small Arms Fire Against Low-Flying Aircraft

Mathematical models for hit probabilities of small arms fire against low-flying aircraft are developed with the aid of the impact points. Three techniques of fire are examined. A model for determining appropriate lead angles is developed. Probability of hit for single shot at various ranges and constant altitude are calculated. Repeated shots are then examined when the technique is used of firing multiple rounds at a fixed angle. The result shows the probability of one of the shots is high, while for other rounds it declines very sharply. Suggestions for further extensions are included.
