well the big key difference in the radar detectors in real life u-boats and the SH3 radar detectors... the real life radar detectors just told you that radar was detected - thats it
there was no bearing to the radar signal, nor was there a range to the radar signal, nor did you know if it was friendly or enemy... all you know is that someone somewhere is using radar.
In SH3 if you have map contacts ON - then it will draw a perfect line to where the radar signal is coming from.
odds are the radar signal is coming from an airplane, so the idea is to dive.
if you dive and hear prop beats... you know it is coming from a ship.
try your best to determine his mean course and intercept him... thats really the best you can do.
if you try a slow submerged approach - he might be long gone before you get to him.
