Launching a UUV gives out a "torpedo in the water" warning to the other units in the area. So not very usefull for stealth in some situations. But yeah, it works similarly in the TMA screen. The bearing lines are plotted from where the UUV is. So this works by lines depicting the direction from where sound comes from and how they intersect.

WAA in real life works I think by analyzing the signal delays between a lot of smaller sensors in the array. And by doing (long-term) signal processing on various frequencies it can figure out the phase (the position in the wave, think of it as the second hand on the clock going round each minute for each wave period) of particular frequencies. From these slight delays it can reconstruct the distance from where it must have originated. As it's exact workings are no doubt classified you might as well consider this magic.

WAA in the game simply gives the bearing and range of the contact with some random noise added to it. Or so it appears. Who knows how Sonalyst calculated this exactly.
