Detrimental Effects of High Side Lobes in a Reverberation Field

Abstract

The AN SQS-26 sonar system is analyzed after failure of certain elements to determine if signal loss caused by decreased beam pattern response, and noise level change caused by reverberation level change are sufficient to declare a system failure. A system failure criterion is established in terms of the change in the output signal-to-noise ratio (S/N) from the beamformer. The input (S/N) of a properly operating sonar is considered as the reference, and the decrease in (S/N) caused by element failures is presented.
