PS. Air pig is correct about the detection mentioned in RV Jones' book. However, there was a lot of work going on that is not all listed so, whether other chaps flew balloons (blimps?) for such purpose may be listed somewhere else?
I believe they did have chaps climb the Chain Home radar towers to try to detect the beam signals.
