In a target tracking system wherein a television image of a target is used for guidance of a missile toward the target, a method of compensating for undesirable missile body motion and providing a stable television image output from the television camera to the missile target tracker, comprising the steps of:

  • rigidly mounting a video camera to the missile body;

    directing the camera lens along a field-of-view that is referred to the missile longitudinal axis;

    deriving a television image of a target within the field of view;

    sensing missile body disturbances;

    providing missile pitch and yaw angular velocity signals in response to said disturbances;

    processing said angular velocity signals;

    coupling said processed angular velocity signals to a television camera'"'"'s vertical and horizontal deflection coils and;

    moving the camera scanning raster of the television camera in the opposite direction of undesirable missile body motion for providing said stable image output to the missile target tracker.
