Abstract
1. In an electro-mechanical bearing computer in which the bearing angle of target relative to a predetermined line is computed from the time interval between the arrivals of a wave front at two spaced locations and a constant voltage proportional to the distance of separation of the spaced locations, the velocity of propagation of the wave front, and the angle of inclination formed by the intersection of a line drawn through the spaced locations and a horizontal plane through one of the spaced locations, PA1 A. means for generating a first signal proportional to said time interval, PA1 B. means for generating a second signal proportional to said constant voltage, PA1 C. first resolving means connected to said first and second signal generating means for providing an unmodified third signal equal to the difference between said first and second signals, PA1 D. third signal detecting means connected to said resolving means for providing an error signal when said third signal is not a predetermined value and for providing a null signal when said third signal is said predetermined value, PA1 E. means connected to said resolving means for modifying said third signal and providing an indi…
