Uncertainty in standard sphere calibrations
Abstract: In fisheries acoustics, the standard sphere method of echosounder calibration is most ... commonly used (Johannesson and Mitson, 1983; Simmonds et al., 1984). To investigate the uncertainty in the ... variations in the system gains of 0.3, 0.2 and 1.5 dB, respectively. Additionally, system gain values ... calibrated with the 30.5 mm Cu sphere were consistently lower than those with the 33.2 mm WC sphere. Prompted ...
