Abstract
Abstract A passive or semiactive homing missile using an optical sensor. The sensor includes a wide-angle lens and a quadrature detector. When a moving target is acquired, signals are generated to turn the missile toward the target. These signals are integrated and are used to turn the sensor to lead the target. The missile will eventually settle on a constant bearing (collision) course with the target. If the target makes changes in speed or direction, the missile will change direction to re-establish a collision course to the target.
