Abstract
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.
