Stereoscopic Mapping of the Seafloor by a Towed Two-Fish Side-Scan Sonar System.

Abstract:

Sea trials were conducted to test the concept of constructing a seafloor contour map by interfacing a manual stereo-sonar plotter with a digital computer. The at-sea work used a pair of 100-kHz, side-scan, sonar fish towed at a lateral separation of 42 feet. Real-time data on near-bottom scanning contained mutual interference effects which prevented the stereoscopic fusing of corresponding sonar images. System component errors were obtainable with repeated scannings of an artificial target array. Modified author abstract
