Experimental data for a 5MHz acoustic measuring probe: partⅠ

This is the data base about the study on a newly developed acoustic probe. The frequency of the probe is 5MHz. The sand sample used in the study is relatively small and all come from Changjiang River. BSI means back scattered sound intensity, SSC means suspended sediment concentration. Exponential method and power method are put forward to the fit of the experimental data, the correlation coefficient and parameters of the two method are calculated. This data base including: (1) recorded time-averaged BSI of each group with different SSC. (2) changes of recorded BSI plot against SSC. (3) calculation table for correlation coefficient of exponential method and power method. BSI is obtained from analyzing time domain signals.
