So I found this guide (link below) which I found to be easier to follow than the guide with the game.

I successfully used this to determine the bearing of an enemy while sitting still. What I can't seem to figure out is how to use this method to do the same while moving.
I am sure I am missing something simple here. Can someone point me to a similar guide for use while moving?
Thanks in advance.
