The research and development carried out by the staff of the Opočinek Research Institute continued the work in the field of radar (RL POHON-A and POHON-E) and with the type RPL-2A launched a successful series of types and modifications of radar landing systems for military and civil airports.
The RPL-2A radar system kit consisted of:
a) the RL-2A aerodrome (surveillance) radar
- Pulse power 160 - 200 W.
- Range up to 40 km.
- Accuracy of target coordinates in range +/- 5%, in azimuth +/- 1.5%.
Located at least 350 m from the RP-2A antenna unit and outside its working sector.
b) of the RP-2A landing radar
- Pulse power 160 - 200 W.
- Range up to 20 km.
- Accuracy of target coordinates detection in distance at km markers 3% of distance, in heading 0.6% of distance + 10% of deviation from the axis, in position angle 0.4% + 10% of deviation from the axis.
It shall be positioned 600 - 1 500 m from the VPD axis.
(Both RLs operated in the frequency band 9.15 - 9.6 GHz i.e. 3 cm).
c) evaluation site
- remote control of both RLs. It can be up to 1,500 m away from the antenna units on the basic cable amplifier (additional 1,500 m if another cable amplifier is inserted). Includes:
- Control unit and RP-2A indicator (430 mm diagonal screen.
Rectangular display angle - distance. Position angle sector at the top, position angle sector at the bottom.
The descent axis is continuously selectable from 1° to 5°.
- Control unit and indicator RL-2A (screen Ø 250 mm. Distance ranges 15/40
km, markers 5/1 km.
The workstation is located on the LRLP or in the landing controller's vehicle (LCV).
d) 3 cars Praga V3S(2 box, 1 barge with tarpaulin).
e) 2 power plants EC 7,5 kVA /ZB-8
+ 2 500 Hz current converters. The source units (inverters) are located near the antenna units.
- Power supply is possible (when using inverters) from the mains 3x 380 V/50 Hz
