That all by itself is useful for TMA purposes. If you looked at your broadband screen and saw his bearing changing over time, while the doppler over time said something else, you could paint a picture much quicker.

But about finding a speed with a doppler shift on target frequency will be MUCH MORE difficult than to use a simple TMA.
As said compressioncut, to use calculations based on doppler shift will need to double the size of the manual.

That's probably true... but the manual is short on calculations anyhow. It really doesn't convey how mathematically intensive naval warfare CAN BE. Calculations are a part of warfare in general, and naval warfare especially. I don't really have a problem with that, though, because that's not what the manual is there for. The manual for the simulator should be enough to get you up and running. That's it. The manual we have does that.
It's up to the ASW geeks like us to write supplements, develop tactics, design scenarios, etc. which will allow the children to learn the real depth of what's provided.
But... unfortunately... we have no useful Doppler effect in DW.

Doppler is only used as range finder for distant galaxies, because the expansion factor is already estimated.
