The paper presents a method for imaging from the data obtained from a synthetic aperture radar that does not utilize spotlighting. The SAR database, that is commonly encountered in reconnaissance imaging with stripmap SAR, is passed through a digital spotlighting algorithm for range and cross-range gating. The resultant filtered SAR data is used in the high-resolution spotlight SAR inversion to image the desired target area. A subaperture processing and coherent imaging method to implement the algorithm is presented.<>
