Abstract
The author addresses transfer alignment for synthetic aperture radar (SAR) under conditions of nonrigidity between the master INS (inertial navigation system) and the radar antenna. A generic transfer alignment simulation is described, with results given for sample cases with and without rotational vibration. The author presents a design concept representing a radical departure from preceding approaches to SAR transfer alignment: Kalman updates are allowed during a frame. This allows small high-frequency changes in the velocity history so that buildup of low-frequency errors will be counteracted
