the key here is consistent return. anything looking down at a horizontal wing would have to be in a vertical or near vertical position to the plane itself which is extremely unlikely. but even if it gets a instance of return, the plane continue to move and change the angle.
Yes, but if the satellites worked as a network instead of individually then there would be many reflections in many directions, and many satellites to detect them, no?

In theory, yes.

In practice, very demanding. You are suggesting a Starlink kind of radar constellation. Starlink's very low earth orbit satellites orbit at 340km which is about the AWAC's working range (horizon at 10km altitude). However AWAC's radar antenna is huge. Even though RCS return of top view of the aircraft is also large, but the satellite's antenna is tinny in comparison. Besides a Starlink kind of system at this altitude need over 7500 satellites to provide always over head coverage to monitor a quick moving target. Remember for Starlink to work the satellite does not need 90 degrees over head because it uses AESA to track and aim at the receiver. This works once they are in sync. However, an enemy aircraft is non cooperative, the satellite must be over 90 degrees on top to be able to find the aircraft, that is a lucky shot. Tracking afterwards is easier, but finding is difficult.

Man.. My 500000000 node aesa must not be working. Tell you what though it isn't fun having them run randomly

Wasn't there some reports of H-20 undergoing taxiing earlier this year? It's certainly possible that this is H-20 given the timeline. There is really no other obvious aircraft program that fits the same description.
