1.      Class of Equipment. The TPS-34 is a high power, air-transportable surveillance and control radar operating in the D-band of frequencies. It has integral height-finding using the V beam principle and several anti-jamming and anti-clutter facilities are available.

2.      Purpose of Equipment. The TPS-34 is used by the RAF for control and surveillance in two situations:
a.      In static sites overseas.
b.      In tactical deployments at short notice to unprepared sites.

3.      Frequencies. Overall 1,250 to 1,350 MJIz (D band).
a.      Vertical Beam-Tuneable in the D band range.
b.      Slant Beam-Tuneable in the D-band range.

4.      Coverage.
a.      Azimuth. 0^o to 360^o in continuous scan.
b.      Elevation.
(1)     0^o to 45^o for detection.
(2)     0^o to 30^o for height finding.

5.      Range Performance. An 80% probability of paint on a 15 square metre target at 220 nm at 44,000 ft. Height finding capability to 240 nm.

6.      Radar Accuracy.
a.      Range. ± 1%.
b.      Azimuth. 1^o ± 0.3^o.
c.      Elevation:
(1)     + 2,500 ft at 125 nm at 45,000 ft.
(2)     ± 3,500 ft at 125 nm to 200 nm at 45,000 ft.

7.      Discrimination.
a.      Range. 0.5 nm.
b.      Azimuth. 1 .6^o

8.      Aerial Characteristics.
a.      Polarization.
(1)     Vertical beam-horizontal.
(2)     Slant beam-vertical.
b.      Horizontal Beam width.
(1)     Vertical beam - 1.6^o
(2)     Slant beam - 2.3^o

9.      Aerial Reflector. Double-walled, fibreglass, shaped, reflector with dual reflecting surfaces sensitive to polarized radiation, giving two separate beams. Assembled from 22 component sections.

10.     Aerial Feed. Two separate horns are used:
a.      Horizontal-polarization-sensitive for vertical beam.
b.      Vertical-polarization-sensitive for slant beam.

11.     Scanning Rate. Clockwise (viewed from above) at 6 rev/min.

12.     Transmitters.
Two transmitters are used, one for the vertical beam and one for the slant beam.
a.      Type. Magnetron.
b.      Pulse Width. 6 uS.
c.      PRF. 295 pps.
d.      Peak Power. 4 MW or better.
