摘要： A rate gyro (10) is arranged in a seeker head of a missile and is stimulated to nutate with its natural nutation frequency in inertial space for the purpose of scanning a field of view. The rotational frequency and the nutation frequency of the rate gyro (10) relative to the missile are determined. The roll rate or roll angle is achieved by subtraction of these frequencies multiplied by suitable factors depending on the gyro in a roll measuring circuit (32).

摘要： In a seeker head for target tracking missiles or projectiles, an imaging optical system with an optical axis is mounted on a rotor. The rotor is mounted for universal swivelling motion in the missile. It rotates about its geometrical axis. Thereby, the rotor is stabilized in inertial space as a gyro. The optical system images an object scene on a circular array of detector elements. The rotor can be caused to make controlled precession and nutation movements by control loops with attitude pick-offs and a torquer coil such that the optical axis of the optical system makes a cyclic spiral movement over an extended field of view, in a seeking and target acquisition mode, is then precessed towards a detected target, the nutation amplitude, in a pre-phase mode, being made equal to the target deviation, and, eventually, in a target-tracking mode, makes a circling movement within a limited area in the field of view containing the target. In the target-tracking mode, the target image circles on the circular array of detector elements.

摘要： A projectile for launching by a cannon or by a launcher is obtained by an expedient combination of features. An optical seeker has a gyro mounted on an air bearing and an optical detector. a Cassegrain system is arranged on the gyro as imaging optical system and scans a field of view with a gyrating scanning motion. At its tip, the projectile is closed by an optically transparent wedge, which is limited by planar surfaces. The optically transparent wedge carries a central spike. The projectile has tail stabilizing fins and steering by wings arranged near the center of gravity of the projectile. The wings are controlled by signals from the detector through signal processing means and an actuator system. The projectile is shaped make a continuous roll movement due to aerodynamic forces.
