Abstract
A method for constructing focused radar images includes chopping the radar illumination period into p sub-periods, two successive sub-periods overlapping temporally; choosing n successive sub-periods from among the p sub-periods, and for each of the n chosen sub-periods, performing radar acquisitions to generate an image IM_0x of resolution R0; and applying an autofocus processing to each of the n images IM_0x generated; combining the n images so as to generate at least one new focused radar image IM_1x. The method is applied notably to the production of high-resolution SAR images with the help of an aircraft equipped with a radar antenna.
