IJN sonar parameters

I was reading this thread

http://www.subsim.com/radioroom/show...r+capabilities

on sonar and I'm wondering how much (if any) of this applies to SH4? Specifically, I am curious as to the parameters of the active search cone and whether you can travel under it or outside the width of the beam to avoid detection. Is there another thread that discusses this with respect to SH4? I tried a few searches but didn't come up with anything other than the above link.
