In the MoBo forum there's a stickied thread:
Tutorials and Examples
One of the links in the thread is titled: "TMA While Moving"
Just take a look at my responses, explanations, and MoBo plot pics for that example and it should start you off in the right direction. Of course, there's a number of other examples on that thread you might want to review as well.
If you still have questions, submit a scenario

to the
MoBo Forum (target, bearing, speed, distance, etc.) as a new thread and I'll try to help you out.
