Insights into SAR signatures for target acceleration maneuvers

This paper examines the synthetic aperture radar (SAR) imagery morphology of signatures induced by surface targets that are accelerating from a lower to higher speed during the collection interval. Recent studies have revealed that such moving target smears are not constrained to have the simple shapes of mere parabolas but instead can display a rich variety of two-dimensional (2D) shapes, including self-crossing signatures. The present analysis provides new insights into the nature of such complicated SAR target smears via comparison with the asymptotic parabolic signatures resulting from the initial and final segments of approximately constant-velocity target motion.
