Some Computed Effects of Dome Skin and Temperature Differential on Operation of the AN/SQS-26 Sonar Equipment.

摘要

An analytical investigation of limited extent has been conducted to obtain estimates of the effects on AN/SQS-26 sonar equipment operation caused by (a) phase distortion in an incident signal resulting from the passage of the signal through the dome skin surrounding the transducer; and (b) phase distortion in an incident signal due to a temperature differential existing between the salt water inside the dome and the surrounding sea water. It was felt that the possible major effects of these phase distortions on operation of the sonar equipment would be manifested in the beam patterns and bearing error in the Sector Scan Indicator (SSI). The SSI bearing error is used in this technical note as a convenient tool for evaluating the operational effects of these phase shifts.
