Abstract:

This report describes a sonar test unit combining a signal-to-noise ratio SNR meter and a bearing deviation indicator BDI that has been designed and constructed at this facility. The SNR meter operates by clipper correlating the left-half and right-half sonar-array outputs and then converting the correlation coefficient to SNR the BDI operates with a clipper correlator that has a 90 deg phase-shifted input signal. Calibration, installation, and trouble-shooting procedures for the unit are presented. Author
