Fig. 1. (a) Attenuation and (b) half-power bandwidth for selected frequencies in the underwater acoustic ULF band
Figure 2 depicts the maximum Doppler shift for selected frequencies in the ULF range. We assume that the relative speed varies from zero to eight knots.
Fig. 3. Experimental scenarios. (a) Communication between one transmitter and one receiver
Fig. 6. Mobility characteristics for the Doppler shift experiments assuming 1.5 kHz for the frequency; and 0 to 90 ◦ as angle β.
