It looks as though they have taken components of the RWR - Radio Warning Receiver (ARI-18228/1) and integrated them with a rotating antenna.

I can Identify the following (see anotated photo)

Control unit - 17172
Bearing indicator - 17171
Power Unit - 17203
Radio Receiver - 17170

The antenna could be made up of parts taken from the antennas installed on the top of the Vulcans tail - and installed in what appears to be a rotating head.

On the Vulcan there is one of these at each end of the tail fin assemble - one pointing forwards and the other to the rear.

The unit used the discriminated signal from these 2 antennas to work out from which direction the radiation came from and indicated it on the PPI - An audio out put was available on the intercom and the PRF was quite distinctly heard.
