Bellman, upon further review it would appear the sensor is working properly. I can't comment on the specific acoustic conditions or platform details in your test, or on what your interpretation of it is really because I would need to have been there.
One thing that I can say is that the UUV actually seems to be ploting a bearing that is the result of TMA calculations rather than the truebearing from the sensor surface.
You can notice this most clearly if you fire a torpedo past your UUV, or on any contact with a high bearing rate on the UUV. There is clearly a big lag on the bearing of the contact, however, the real bearing is displayed if you drop the contact.
Unfortunately, there is nothing I can do about that, most likely, other than to say, that's the consequence of the new less omniscient aTMA system. I mean, the UUV is giving you free data more or less anyway, so dropping the contact if you really need to be sure of the bearing doesn't seem like TOO big a deal, considering it will pop right back up at the correct bearing.
So, maybe consider it, "working the UUV."
In any case, please run your test again and try dropping the contacts before you take your bearings, and better yet, can you send me the mission file itself, please?
Cheers,
David
PS Also, keep in mind, the sonar on the UUV is always assumed by the sim to be doing detection on base tonals like 50hz or 60hz, so I have to adjust the sensitivity based on detection as if it is a TA! The good news is that I can get the same kind of performance if I have the NRD lowered to a very low level. For example the TB-29 is at -14, and TB-16 is at -10, and the UUV sensor is at 7. (and that represents increments on a log scale, not linear). This means that very quiet contacts may not be detected at all or only at extremely close range. In short, you probably are not going to find a Kilo Imp moving at 3kts in 75ft of water with a UUV at all, and a nuke in the open ocean at creep speed only very very close. It is probably more a useful recon tool for general situational awareness to send it to sprint ahead and triangulate with ownship sensors or to see around and over obstacles. In ASW, it is probably only good AFTER the shooting has started to keep track of your opponent's evasion.
