Match-Mode Autoregressive Method for Moving Source Depth Estimation in Shallow Water Waveguides

Figure 6

Normalized depth ambiguity functions with an insufficient range span for the shallow (Zs = 4 m) and deep (Zs = 50 m) sources. Source depths are estimated by SAB with different SNR in (a), (c), and (e). Source depths are estimated by MMAR with different SNR in (b), (d), and (f).
