摘要:

An acoustic signal from a cw source towed near the sea surface produces a Lloyd’s mirror type of pattern. The signal received on a six‐hydrophone moored array gives a record of this three‐dimensional pattern. A comparison of the observed data and calculated pattern using the characteristics of the ocean provides some insight into transmission in a region where the velocity is depth dependent.
