Figure 10.6 Sample reverberation versus time plot generated by the NISSM active sonar model. The bottom bounce contribution is readily visible in the bottom reverberation curve. The convergence zone contribution is evident in both the surface and volume reverberation curves (Weinberg, 1973). (The reverberation levels are reported here in dB re: 1 dyncm-2. To convert to levels in dB re: 1 |xPa, add 100 dB to the levels shown in the figure.)
