What I don't understand is why the Chinese didn't just have tons of noisy boats near the US vessel. Sound travels well underwater, but the distance between the sub emitting an acoustic signature and the US vessel is large. The distance between some crappy 20 year old barge that's making tons of noise is small and the US vessel can be much smaller. If you got a couple dozen fisherman chugging along a few hundred yards away, wouldn't that accomplish your goal without causing an international incident?

Frequencies and signals processing algorithms. One reason the US is ahead is not so much the gear as the signals processing. How do you think they got a bunch of sonars on the bottom of the ocean between Bermuda, Iceland, Scotland and the Azors to cover the entire atlantic ocean? For example, when the Scorpion sank they were able to ID the location.
