1. A guidance system for a missile having a velocity vector, said guidance system comprising:

  • first means for transmitting a plurality of first radar signals at an area including a target and background clutter;

    second means mounted on said missile for receiving reflections of said radar signals from said target and said background clutter at first and second angles relative to said velocity vector and generating second signals in response thereto;

    third means for processing said second signals and constructing a three dimensional sensed image in response thereto, said third means including;

    means for processing said second signals and providing a plurality of third signals representing range as a function of said first and second angles and a plurality of fourth signals representing intensity as a function of said first and second angles,means for storing said third signals to provide a range image,means for storing said fourth signals to provide an amplitude image;

    fourth means for providing a three-dimensional stored image including;

    means for providing a first reference map for elevation profile andmeans for providing a second reference map for amplitude;

    fifth means for comparing said range image to said first reference map and providing a first error signal in response thereto;

    sixth means for comparing said amplitude image to said second reference map and providing a second error signal in response thereto;

    seventh means for processing said first and second error signals to provide a third error signal which represents a difference between an aimpoint of said missile in said sensed image and an aimpoint of said missile in said stored image; and

    eighth means for generating guidance correction signals for said missile from said third error signal.
