I'm not sure why the FAA would have 3 radomes next to each other like that.
My Googling suggests it is a facility operated by L3Harris Technologies'
Randtron Antenna Systems unit which is based in Menlo Park. So I'd naively
say it's an R&D facility for them, which also adds up with all of the
experimental licenses there. It carries an address of 10700 Cahill Ridge
Road. San Mateo County zoning documents describe it as a "radar test range
facility."
