Avia-D/Koren

The Avia-D/Koren was an L-Band En-Route and Air-surveillance radar built in the former Comecon under participation of the former Soviet Union, Eastern Germany and Poland. The primary radar was a frequency diversity radar built by Unitra and PIT (both Poland), the secondary radar “Koren” (Kyrillic: « Корень », meaning: “root”) built in Soviet Union. The scopes and the operators workstations are built in Eastern Germany.

The first installation was in 1976 at the Airport Berlin-Schoenefeld, near the small village Rotberg. A modernization was carried out in 1986. This radar was operational until 1998.

Avia-D consists of four main components; antenna unit, transmitter unit, the receiver unit with the indicators, and the power unit. The antenna set was mounted on a tower of approx. 20 m height. The antenna has a parabolic reflector with dimensions of 12 m • 4 m. The transmitter used two magnetrons for pulsed RF-generation. The accuracy of the measured coordinates was 1 degree in azimuth, and a distance of 1 percent of the the displays maximum scale.[1]
