Radio troops
The radio technical troops (Futt) were a branch of service of the former air forces of the NVA that the low-flying aircraft reporting service , radar vectoring service and today's mission control service of the Air Force of the Armed Forces was comparable. They were divided into remote radio technical posts, radio technical companies (FuTK) and radio technical battalions (FuTB).
The weapons deployment was not directed directly through the FuTB command post , but rather through the superior command post 1st LVD or 3rd LVD using the radar data provided by the FuTT and the ARKONA (FüWES) air situation data .
tasks
The units and associations of the FuTT were deployed nationwide on the territory of the GDR and, as a contribution to the duty system of air defense (DHS), ensured a complete radio measuring field with defined (for the individual levels of combat readiness ) upper and lower limits. This was measured at a radio measuring field lower limit , which could be shifted down again (to an altitude of about 50 m) by quickly relocatable radar stations.
Radio measurement technology
According to their frequency range, the surveillance radars were divided into
- Meter wave radars,
- Decimeter wave radars and
- Centimeter wave radars
The principle was enforced that the airspace with all frequency ranges had to be cleared up in parallel. This should make the application of active interference more difficult, since hardly all frequency ranges could be disrupted equally effectively.
The altimeter was only available as a decimeter and centimeter station. Their name is derived from a Russian abbreviation:
- PRW: (Russian) ПРВ - передвижной радиовысотомер
- (German) relocatable radio altimeter (height finder)
The emphasis on "relocatable" referred to the difficulty during the development of these radar devices in creating a stable base that was unaffected by the vibrational energy of the pivoted antenna. This was achieved through the use of heavy artillery mounts as landing gear for this type of radar device.
Ground radar devices from the former NVA
| Surname | NATO code name | Brief description | Antenna silhouette |
|---|---|---|---|
| Meter wave radar devices from FuTT | |||
| P-3 | Dumbo | Forerunner of the meter wave stations of the NVA, very probably not used in the NVA, but in the GSSD . |
|
| P-8 | Knife rest A | First meter wave station, in use until 1963, detached and guyed tubular mast with four Yagi antennas |
|
| P-10 | Knife rest B | narrow lattice mast on the vehicle, also four Yagi antennas |
|
| P-12 MA | Spoon rest A | stable lattice mast on the vehicle ZIL-157 with 12 Yagi antennas |
|
| P-12 NP | Spoon rest B | Trailer version with two Ural traction devices | |
| P-12 NA | Spoon rest C. | stable lattice mast on the vehicle ZIL-131 | |
| P-12 AMU 14 | P-13 | a P-12 on an antenna of the P-14 |
|
| P-14 | Tall King | large stationary parabolic antenna (33 m × 22 m), e.g. B. FuTK-333 Putgarten (on Rügen) and FuTK-312 Dobra / Großstöbnitz (near Altenburg) | |
| Oborona (5N84A) | Tall King C. | Successor to the P-14, with a similarly sized antenna | |
| P-18 | Spoon rest D | partially transistorized, 16 Yagi antennas, antenna in 1.5m steps variable antenna height |
|
| Decimeter wave radar devices from FuTT | |||
| P-15 | Flat Face A | two smaller parabolic mirrors on top of each other |
|
| P-15 AMU | Squad Eye | with a special antenna on a detached high lattice mast (15 or 30m). Contrary to the NATO code designation, this was not an independent radar. The antenna with the mast was only an accessory of the P-15. | |
| P-19 | Flat Face B | Further development of the P-15, integrated secondary radar 1L22 |
|
| Kabina 66 (5N87) | Back Net | two transmitter / receiver cabins, each with two antennas with beam direction offset by 180 ° |
|
| ST-68U | Tin Shield | 3D radar device, digitized signal processing |
|
| Centimeter wave radar devices from FuTT | |||
| P-25 | Strike Out | rotatable broadcasting booth with two very stable Cosecans² antennas (made of solid sheet metal, the upper one inclined by approx. 15 °) |
|
| P-30 | Big mesh | Inclination like the P-25, but lighter antenna structure, with additional antenna for active response | |
| P-35 | Bar lock | like P-30, but parallel antenna structure, with 6 waveguides to the antenna (stacked beam cosecans² antenna), also with active response |
|
| P-37 | Bar lock | like P-35, with 5 waveguides to the antenna, also with active response, later with IFF bars on the upper antenna | |
| P-40 | Long track | Radar device of the land forces (army) on an armored tracked vehicle (426U), hydraulic antenna installation and removal. |
|
| Radio altimeter from FuTT | |||
| PRW-9 | Thin Skin A | Height finder for low-flying targets, very narrow, massive parabolic antenna, used around 1972 |
|
| PRW-9A | a PRW-9, based on a KrAZ-214 truck | ||
| PRW-10 | Rock Cake | first height finder of the former NVA (from 1963/64), wider and massive parabolic antenna (perforated sheet metal) |
|
| PRW-11 | Side Net | Successor of the PRW-10, wider, more filigree parabolic antenna, reflector made of riveted metal rods |
|
| PRW-13 | Odd pair | Successor to the PRW-11, larger parabolic antenna with a smaller compensation antenna |
|
| PRW-16 | Thin Skin B | Modernization of the PRW-9 ; for the air defense ( TLA ) built on a KrAZ-255 truck, for the intelligence and air traffic control troops as a trailer version |
|
| PRW-17 | Odd Group | like PRW-13, but with several compensation antennas |
|
organization
(Status at the end of 1989)
Technically, the radio technical troops were subordinate to the chief radio technical troops (chief FuTT) in the command of the LSK / LV . This led the troops via the chiefs of radio technical troops of the 1st and 3rd air defense divisions.
