Gyurza SHORADS

[World B4]

The Gyurza system was an upgrade for the Strela-10, the most defining feature of which being the L-136 MAK-F aircraft detection system. I have been unable to find any info regarding the use of such a system, usually used in aircraft, on other land based telars. What I want to know is if the system hardware was designed for the Strela-10 upgrade, if it was a preexisting aircraft system "bolted on" or what combination/mix and match thereof.
