AWACS is sitting at long range and firing active search radar from single direction. To get a proper coverage of area, you'll want to have as much data from as many data points as possible which are interlinked and share radar data. This makes both active jamming and stealthiness much harder to execute. This ranges from flying hugging ground to actually flying stealthy planes to avoid detection.
Incidentally, that is exactly what both NATO and Russian tech developed into back in the 1980s and 1990s.
