Abstract

SAR processing has revolutionized radar imaging over the past 35 years. SAR techniques are now being applied employed in sonar processing; the enabling technologies being adaptive focusing techniques imported from the SAR world. Synthetic aperture sonar (SAS) produces acoustic images with high resolution that is independent of range. Moreover, within the limits of diffraction, that resolution is also independent of frequency, thus making available a wide engineering trade-space within which sensor performance may be optimized.
