Abstract
A synthetic aperture radar system includes a distortion correction device arranged for autofocussing of raw data by contrast maximization. Reference functions are selected on the basis of a range of trial accelerations. The acceleration producing the highest contrast is taken as the current radar platform across-track acceleration. This information is used to generate phase and range corrections for the data.
