Figure 6

Functional positional array example with (a) a 400-m maximum effective detection range and no CPDI effect considered and (b) a CPDI effect with a 200-m minimum effective detection range and a 400-m maximum effective detection range considered. In example (a) and (b), i) shows the expected detection range, with gray areas showing the extent of minimum effective detection range, ii) shows the effective acoustic coverage in yellow, effective positional coverage in green and acoustic coverage dead zones in red, iii) shows the number of receivers giving effective acoustic coverage across the bay, with red showing zero, yellow showing one, orange showing two, green showing three, and blue showing four receivers.
