The biggest problem with SH3 detectors is that the self-noise apparently affects the active sonar. Or otherwise silent running effectively eliminates the detection, which should be properly guaranteed.

Another thing is, that there´s no ship at all which is equipped with an "AI_hydrophone" . Don´t know for which reason these "AI" sensors are contained in the AI_sensors.dat. Maybe a relict from testing phase or even older parts (SH2?).

I am inclined to believe that the "AI default hydrophone" is hard-coded detector, which is present in each unit. Note that the vast difference in the detection of u-boat between stock SH3 and GWX is only one difference: Change MaxRange from 600m to 7km.

I also tested without rig for silent running, because afaik sonar detection is not sound dependant (there´s no sound factor within sim.cfg, in contrast to the hydrophone settings). But I know that there´s an aspect dependant detection of the sonar.

Therefore, this aspect of the tests used to set the value of 0.1 m, which guarantees that the game does not reject the detection of u-boat if other conditions are met. It did not matter whether I set this for each of sonars individually or set the default value when all sonar models will have a 0m2 value aspect.
For a long time trying to eliminate the influence of silent running on the sonar and still this effect does exist.

Stiebler always uses an aspect of 100m², but in earlier tests, i only realized a difference between bow on and bow off at a minsurface of 50m.

For such a big weakness sonar is a better approach in my opinion, underestimating this value to sonar detect better than overstating it to detect worse. From what I know in reality the Allies sonar technology was very efficient, but in a passive targeting were much weaker than the Germans. That is why the game should reflect this.
