ABSTRACT:
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.
