My guess is that it is a space surveillance station.... not only are there a lot of dish antennas, but those funny spheres on top of poles showed up in a movie about a space surveillance station some years ago---can't remember the title, but it starred Jodie Foster. They aren't located to light anything special, but instead seem to be around a perimeter fence. Part of an intrusion defense? Maybe. From the vegetation it looks like the climate is normally dry...?
