%X Autofocus is an important technique in high resolution Synthetic Aperture Radar(SAR). When autofocus is needed by real-time SAR imaging processing, it must be very computationally effective. Shift and correlate algorithm is such an algorithm. It was first presented by Jorgen, (1991). In this paper, we analyze its essence and make some advance on it.
