I don't know about these specifically, but similar systems the military used are interesting in that they have components you didn't see much in other systems.

I don't know about these specifically, but similar systems the military used are interesting in that they have components you didn't see much in other systems. Like "traveling wave tubes" and klystron based amplifiers. The systems I'm familiar with were at temporary "forward air control" posts, where a radar system was installed relatively close to the front lines. The portable microwave transmitters were used to relay the radar data and voice calls back to the generals further back from the front lines.
