TEST RESULTS USING A PROTOTYPE SYNTHETIC APERTURE SONAR

The operation is described of a prototype coherent synthetic aperture sonar (SAS) based on continuous transmission frequency modulation that covers a 1-octave bandwidth. Images calculated from real data (collected from a sonar range in Loch Linnhe, Scotland) show that it is now possible to produce high-quality images of the seafloor at realistic mapping rates. An air-filled steel buoy was used as a test target, and several images are shown of this target using a variety of reconstruction algorithms.
