PRW-13
The PRW-13 ( NATO code : Odd Pair ) was a fully remote-controlled height finder from Soviet production for height ranges of up to 85 kilometers, which was adopted by the German Armed Forces as an interim solution for the new federal states and was reliably in service until 1998 despite major spare parts difficulties.
A special feature is its compensation antenna , which is used for sidelobe suppression and was sometimes referred to as a baby antenna or kangaroo arrangement .
The PRW-13 worked with a magnetron on a fixed frequency, a second transmitter was on standby with one of four reserve frequencies which, for reasons of confidentiality, could never be used before the takeover into the Bundeswehr.
In terms of technology, the PRW-13 consisted of the tried and tested tube-fitted assemblies of its predecessors, mixed with partially transistorized assemblies and with assemblies with integrated CMOS circuits.
