A Signal-to-Noise-Ratio, Bearing-Deviation-Indicator Meter Unit Utilizing Clipper-Correlator Circuitry.
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)
