How dangerous is to use active sonar?

You would be correct for single leg TMA. To get a single solution for speed you would do multi-leg TMA.

The Eckelund method does not require any estimate of target speed, it provides range only.

I am not sure when the specific techniques I previously was familiar with were developed, but I agree they would be tough in WW II era subs.

You mean, collecting a series of bearings, then turning your own course and then collect a few more?
