HF Sonar on subs

Anyway HW sould be detectable by active sonar threat detector (how the hell is it named ? One play the game ALL the time and can't remember). Since it can detect torpedoes pinging at 22khz, it should detect HF sonar too. Also, if torpedo pings on 22khz, does it mean that the pings you hear are generated by the threat detector ?
And once more please .. should not be pings and ping returns visible on broadband waterfall ?
I could understand that active sonar screen uses narrow frequency filtering so you can see only return from your own ping there. But on BB there should be NO filtering.
