It's called the 0-degree AOB method and is referenced as a SOP in the U.Kdt.Hdb, a tactical manual given to sub commanders by the Kriegsmarine. In fact they recommend it for every attack.
1. Intercept target
2. Get in front of target, keep taking bearings in regular intervalls, distance doesn't matter at this point
3. Cross in front of target. 0° AOB bearing -> true heading on map, and all the bearings now cross the true heading. If you've carefully taken bearings you will have a very exact speed estimate from the map.
4. Attack
I almost exclusively use this method, except when I surprise a target somehow I go for a "shot from the hip".
Check out my let's play
where I demonstrate this method many times.
Greetings, and good hunting!
