An Analog Computer Study of the Effectiveness of Interceptor Commands Derived from a Prediction Equation of Second Order
NASA Memorandum 10-7-58A from Ames Research Center presenting an analog computer study comparing first-order and second-order prediction equations for automatic interceptor guidance on lead-collision courses against maneuvering targets. The authors derive second-order prediction equations that allow the interceptor to fly a straight-line course against a target with constant acceleration, then use an analog computer to analyze system stability and evaluate rocket miss distance under various conditions including limited/unlimited interceptor acceleration, constant and pulse target maneuvers, and varying rocket speeds. Results demonstrate improved miss distance performance with second-order commands compared to first-order prediction schemes.
