A synthetic aperture radar in which echo returns received at sampling points over the length of the synthetic aperture are stored and correlated to form an image of the reflecting surface. The echo returns taken at sampling points over the first half of the synthetic aperture length are integrated to form a first synthetic monopulse beam, the echo returns taken from sampling points over the second half of the synthetic aperture length are integrated to form a second synthetic monopulse beam, and the first and second synthetic monopulse beams are linearly combined to provide synthetic monopulse sum and difference signals suitable for performing various beam sharpening functions in accordance with techniques in use with sum and difference signals provided by conventional monopulse antennas.
