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

Figure 5

Normalized depth ambiguity functions with a sufficient range span for the shallow (Zs = 4 m) and deep (Zs = 50 m) sources. Source depths are estimated by SAB with SNR = 20 dB, 5 dB, and -5 dB in (a), (c), and (e), respectively. Source depths are estimated by MMAR with SNR = 20 dB, 5 dB, and -5 dB in (b), (d), and (f), respectively.
