Abstract
A guidance seeker for a spinning projectile defined by its angular momentum vector, comprises a lens system or a millimeter-wave antenna for receiving radiation derived from a target and forming an image of the target. The lens system has a reticle having a pattern of concentric circles nutating about the projectile angular momentum vector such that the received radiation is modulated by the target image as the image moves across the concentric circles. The millimeter-wave antenna generates concentric lobes nutating about the projectile angular momentum vector such that the received radiation is modulated by the target image as the image moves across the concentric lobes. A detector is coupled to the lens system or the antenna for receiving the modulated radiation. The detector is adapted to generate an output in response to the received modulated radiation. A circuit is provided to process the output from the detector to determine the deviation of the target image from the axis of the concentric circles or lobes.
