The following is from memory and hearsay – please correct where possible – atchistory
The facilities used by Midland Radar, like Northern and Eastern Radars, was formerly used as part of the Bloodhound air defence guided missile system. All three were virtually identical sites when handed over for use as long range area radar units.
The three stations used the Type 82 radar, with a stacked beam design that enabled height finding without needing separate additional height finding radars. Unlike Northern and Eastern there was no civil ATS cell. I vaguely remember that Midland perhaps provided a Centralised Approach Control Service for a number of military airfields. The photo above shows the cinema style ops room very well, just off screen was a shared data wall. The four console control position suites are shown very well, with the right hand display used for height finding. Some sectors have an additional high level display showing either a longer range display or a second remote radar picture.
Both Northern and Eastern radars feature elsewhere on this site as does the Type 82 radar.
