Introduction to Sonar, Navy Training Course.
Naval Personnel Program Support Activity, Washington, DC.; Bureau of Naval Personnel, Washington, DC.
Fundamentals of sonar systems are presented in this book, prepared for both regular navy and naval reserve personnel who are seeking advancement in rating. An introductory description is first made of submarines and antisubmarine units. Determination of underwater targets is analyzed from the background of true and relative bearings, true and relative motion, and computation of target angles. Then, applications of both active and passive sonars are explained in connection with bathythermographs, fathometers, tape recorders, fire control techniques, internal and external communications systems, maintenance actions, test methods and equipment, and safety precautions. Basic principles of sound and temperature effects on wave propagation are also discussed. Illustrations for explanation use, information on training films and the sonar technician rating structure are also provided. (CC)
