I photographed this AN/GPN 30 / ASR-11 DAS-R Digital Radar in action near the Air Mobility Command in Dover DE.
I believe the base at Dover was currently using the AN/GPN 30 DAS-R Digital Radar (military version of the FAA’s ASR-11), which looks incredibly similar to the AN/GPN 20 Radar on display at the Air Mobility Command museum.
