ATAG's 1st Bomber Night this Weekend

[csThor]

What you are talking about is FREYA. That was a true radar and - contrary to the british CH and CHL - it was mobile and technically slightly more sophisticated (for whatever that's worth). One such set was installed at Cap Gris Nez but it wasn't used for detecting aircraft (Freya was not really good at giving the target height, this is why it was later used in tandem with the more accurate Würzburg-Riese radar) but to monitor british shipping in the Channel.
