1. A radar for acquiring a synthetic aperture image of a scene, said scene having one or more radar scatterers located on a horizontal flat {circumflex over (x)},ŷ

  • plane, said radar system mounted on a moving platform moving at an angle θ

    tilt with respect to said {circumflex over (x)},ŷ

    plane, with a component of motion in a {circumflex over (z)} direction, said {circumflex over (z)} direction perpendicular to said {circumflex over (x)},ŷ

    plane, said radar comprising;

    a radar receiver for digitizing radar returns having a phase from said scene, anda computer for adjusting said phase of said radar returns in response to said θ

    tilt to generate phase adjusted returns and computing said synthetic aperture image from said phase adjusted returns.
