Title:
Some Computed Effects of Fresh Water in the Sonar Dome of the AN/SQS-26

Abstract:
This technical note presents computed results and conclusions on the effects in the vertical patterns produced by fresh water in the dome cavity of the ANSQS-26 at a relative bearing of 80 deg and at a depression angle of 30 deg. Recent tests on the U.S.S. Wainwright revealed serious errors in the vertical directivity pattern for the depressed beam. It has been suggested that the errors were produced by fresh water in the dome. This note presents computed estimates of the errors produced by the fresh water. Also, it was suggested that a temperature differential between the water in the dome and the sea water may have existed. Results of a worst case analysis on the combined effects of fresh water and temperature differential are presented.
