Development of a 120-Degree Sonar Transducer with Sparsely-Spaced Sensor Elements
NAVAL COASTAL SYSTEMS LAB PANAMA CITY FL
Pagination or Media Count:
A 120-degree beamwidth sonar transducer with the sensor elements in the array sparsely spaced is described. The radiational characteristics of the transducer array were investigated through the application of a computer program, and from the investigation it was determined that a sensor packing factor of 52 percent was permissible in the design. The fabrication and assembly of the transducer is described, and evaluation test results reported. An improved transducer array with wide-angle transmission characteristics has been developed for sonar purposes.
