The Model 350 Sonar: A High Resolution, Electronically Scanned, Dual Frequency, Multiple Beam Obstacie Avoidance Sonar

An electronically scanned pulse sonar with discrete, acoustically-formed beams provides the basis for a new line of sonar array instruments with evolutionary growth capabilities. A prototype, designated the Model 350, is being developed and tested as an obstacle avoidance sonar. The Model 350 is an attempt to optimize performance, size, and cost in terms of current technology, with future growth capabilities to solve diverse custom applications in the areas of navigation, surveillance, underwater surveying, and bottom mapping. Specifications, features, and design philosophy are examined in detail, followed by a comparison of operational performance data gathered during the last year. Custom enhancement capabilities for specific applications are covered, with details on typical configurations.
