Synthetic aperture radar (SAR) is a popular tool for long-range imaging of stationary ground objects. Moving targets in the imaged scene will have a mismatch to the matched filter in the image formation process, thus degrading target image quality. In this paper, the impact of uncompensated target motion in SAR imagery is studied in detail. Bounds on allowable target rotation, and random and deterministic translation are derived to maintain image interpretability.
