ABSTRACT:
RF energy radiated by impacting munition rounds is used to provide an indication to a gunner where the rounds from his gun are striking, or to control a gun servo (158) to automatically correct the aiming of the gun. The RF energy from the rounds is received by several antennas (32, 34, 36) in a known geometry and the angle of arrival computed from the differences in the times of arrival at each antenna. The impact locations can be displayed in the existing gun sight, or in a head up display for the gunner. The angle of arrival information can further be used to control a gun aiming servo (158) to correct the aim of the gun to improve accuracy.
