Oooo... you've asked the million dollar question, the real heart of what makes sub simming fun. :-)
There are many ways to determine range, not the least important of which is guessing, or even just determining the upper and lower bounds of a target's range as well as it's direction of relative motion. There's a book called
Naval Operations Analysis that details some of the more sophisticated methods of determining a target's range including Ekelund and Speiss ranging as well as a lot of other ASW geekiness. You can also determine it by taking advantage of simple geometry and make assumptions about the target's speed and how that's related to bearing rate (angular speed in your reference frame). If you're interested in physics and geometry, then this is the really meaty part of the game.

With regards to DW i find i have a hard time getting my ranges acurate. I have watched the video on subGuru's site and it seemed to help but I am looking for some more advice on other methods from some more experienced DW players.
