Which airfield is this (with PAR 2000)?

This is a slide from an ATC powerpoint presentation. Can anyone name the airfield? I'm interested in the old AN/CPN or AN/MPN trailer in the background, if it still exists!

Many thanks

Andy

Possibly Shawbury?
The green portakabin in the background looks like the Cossor CR62 PAR cabin, although the one we had at Farnborough was mounted on the ground, not on another container.
The PAR 2000, now called RPAR, is the dome shaped thingy in the foreground which replaced the CR62. The square chequerboard cabin is associated with the yellow ILS glidepath aerial next to it; nothing to do with PAR.
When the PAR at Farnborugh was withdrawn from use in March 2001 (at least that's when I recorded my last PAR talkdown) due to the runway thresholds being moved, the RAF didn't want the old 'kit' back as it was essentially obsolete; they came and removed the aerials from inside the portakabin but left the shell there for the new airfield owners to cart away.
Shawbury was the RAF school for controllers so for evaluation and controller training I dare say they operated both types side by side for a while.
Soon after it was introduced in about 2002, the RPAR was restricted to VFR operations only.
Unlike its predecessor on which you had to track the aircraft you were 'talking down' using a small joystick, with RPAR, the radar 'locked on' to the target aircraft and followed it automatically. It was available in two basic versions; primary radar only or with an SSR feed. The RAF, being 'cost conscious' (for a change) opted for the 'primary only' version.
It was found however, that at busy training stations where sometimes aircraft in the visual circuit might be scanned by the radar in addition to aircraft in the instrument pattern, the radar would lock on to the wrong aircraft, but there was no means of the controller knowing this!
This resulted in the restriction of its use to VFR only whilst the RAF hurriedly found the funds to modify it by adding an SSR feed so the aircraft to be talked down could be positively identified by the controller.

Many thanks for your response Terry!

Would you happen to know where I could get plans/diagrams for the Gilfillan Brothers AN/CPN-4 or MPN-11 please (cabins, antenna etc.), as used by the RAF, RN & USAFE?

Thanks again

Andy

I think - I'm not sure - that the Gillfillan gear was license built for UK civil airport use in the UK by someone like GEC or Marconi. They used to have at least 2 at Heathrow up until about 1970, but I'm afraid I have no contacts to help.
The CR62 and PAR 2000/RPAR were both originally American designs too.

I found your post during my search for information on RAF PAR systems, such as Cossor CR62 and the predecessors from STC - PAR 3B, 3C & 3D. I believe the picture is of a standard CR62, apart from the paintwork - they were all normally totally green. The cabins were modular with the azimuth antenna system being placed above the main RADAR processing cabin. I have attached a diagram from an orginal RAF training document at No1 Radio School RAF Locking (now closed). I am an ex RAF ground RADAR/Comms technician and have worked on many of the comms systems you will come across on RAF airfields.
