    Abstract: An underwater-acoustic detection problem is studied in which the ambient noise present at a receiver is calculated, given local environmental and wind conditions and local shipping information, as described by AIS data. The signal whose detection is sought is narrowband and transmitted from a source that passes by the receiver along a straight track. Cumulative Probability of Detection (CPOD) is calculated along a series of tracks with increasing closest-point-of-approach (CPA) distances to the receiver. A ‘range of the day’ (Rd) is calculated as being the largest CPA offset for which the CPOD is above 0.50 during target transit past the receiver. Modelling assumptions, strengths, weaknesses and shortfalls are discussed.
