A Digital Lead Computing Optical Sight Model.

摘要

The equations for the lead computing optical sight are developed for implementation in an on-board digital computer. Numerical comparisons are made with a digital model of several lead computing optical sights currently employed on an advanced fighter aircraft. The effects of aircraft roll rate on the lead angle are correctly modeled,which results in significant improvement of the lead angle prediction during maneuvers involving roll. The equations developed are also useful in the implementation of a director type gunsight where the angular rate of the line of sight is measured directly by a tracking device.
