Signature Predictions of Surface Targets Undergoing Turning Maneuvers in Squinted SAR

This paper examines the properties of the signature morphology effects for surface targets that execute turning maneuvers during the collection interval for synthetic aperture radar (SAR) characterized by a non-zero squint angle. Such signatures of turning surface mobile targets often contain a non-zero smear component in the radar down-range direction as well as the more dominant radar cross-range defocus. That is, the residual defocus in the radar down-range direction is much smaller in magnitude than that in the radar cross-range direction. The emphasis of this investigation is an examination of the location, extent, and shape of the signature smear for turning targets for various values of the radar squint angle. The resulting simulations of the SAR signatures give excellent agreement with the theoretically predicted smear contour shapes.
