ABSTRACT:
A synthetic aperture image of a scene is acquired using a radar system. The scene has one or more radar scatterers located on a horizontal flat {circumflex over (x)},ŷ plane. The radar system is mounted on a moving platform moving at an angle θtiltwith respect to the {circumflex over (x)},ŷ plane, with a component of motion in a perpendicular {circumflex over (z)} direction. The synthetic aperture image acquisition requires digitizing radar returns having a phase returned from scatterers in the scene, adjusting the phase of the radar returns in response to θtiltto generate phase adjusted returns, then computing the synthetic aperture image from said phase adjusted returns. The phase adjustment takes into account θtiltplatform motion with respect to the scene.
