Performance evaluation under different external noise conditions. Comparison of estimated results under different noise conditions (40 dB, 20 dB, 15 dB): (a) estimated lateral displacement profiles at the same depth which is marked by the red lines in Figure 3; (b) estimated strain profiles at the same depth which is marked by the red lines in Figure 3 (c) converge curves of average positional error, and the small segments of the curves indicated by the red colour rectangular area are zoomed in displayed in the small panel.
