I think they scrambled your own radar because if you are camping with AC, which is usually the case, they want to make it a bit harder for you to tell where the enemy is coming from, even though if you know how to use the radar you can pretty much figure it out. Like I sadi, it supposedly cant ben seen by PV so they had to introduce a balanced drawback between AA's. But who knows...at SDCC there was no scrambled radar and all ofthis is from videos and interviews I have seen/read so it all very well could have changed when the game went Gold. ANd it still could changes, AC in reach changed a couple of times.
