    $\begingroup$ To be honest, this device shown here is aviation-related (They use it to check the RCS of aircraft/aircraft parts), it is just not a runway. $\endgroup$ Sep 30, 2016 at 22:47

It is not a runway that you see there. It is the US Navy's Radar Cross Section Range at Junction Ranch. From what I know, that is the platform on which they put the object which they want to see the Radar Cross Section of on. There is a radar at the other end of the "runway".

This is what it looks like: enter image description here

  • $\begingroup$ Interesting answer, but it doesn't seem to answer the question of What is this pattern. No downvote here, just saying. $\endgroup$

    $\begingroup$ Looking at the pattern, it appears to be markings on the surface of a turntable and the surrounding structure. The turntable is rotated maybe 55° clockwise from the surrounding structure. The three red lines are probably used to center the landing gear and orient the aircraft on the turntable. $\endgroup$

    $\begingroup$ @JonathanWalters The second sentence in the answer says, "It is the platform..." which does say what it is. $\endgroup$ Oct 1, 2016 at 10:42
