Doubts about radar, planes and anti-aircraft artillery

After attacking a convoy and sinking 3 merchant ships and a destroyer (Strait of Mindoro mission) and spending some time avoiding another, my batteries were at 40% of their capacity. I'm already going to meet another convoy and I need to have a full load. I also wanted to test if I could keep a plane away without having to submerge, but apparently it is not convenient to do that, because either I did something wrong or the gunners do not act automatically in the game. When I had the contacts on on the map, I would see planes marked with a triangular icon approaching, and they didn't take me that much by surprise. I have removed some items to increase the realism to 65% so far. But now they don't appear on the radar screen. I have answered your question friend, but you have not answered mine: does the radar detect or not detect airplanes? If I don't see them on the screen, how can the crew signal a radar contact?
