They used separate disatance and angle displays - an inferior system in most cases as the rotating display better allows the eye-brain system to add value. | |

| Oct 2, 2017 at 13:04 | comment | added | peterG | There are already some good answers here, but I'd just like to add that perhaps, with modern radars in mind, you are underestimating just how useful any kind of early warning would have been at the time, however inaccurate, even from the earliest installations (which I believe used a simple fixed antenna). It was crucial to get the intercepting fighters - with limited fuel - to altitude at the right time. Also I suspect that an experienced operator would learn how to glean a surprising amount of information even from a primitive display such as the one shown in Barry's link. | |

When I was in the Navy in the early 80's we had radars whose design went back to the early 1950's (AN/SPS-10) which were originally designed using lots of vacuum tubes. By the time I saw them the vacuum tubes had for the most part been replaced with solid-state modules which fitted into the same sockets and did the same job, but which contained solid-state componentry for greater reliability. | |

| Oct 1, 2017 at 19:23 | comment | added | Solar Mike | I visited the Dover chalk caves a few years back and there were many radar installations around the coast that overlapped - so a combination of signals and also they were backed up by the observers on the ground as well... Apparently we had a good grip on the technology then! and sorry I deviated from the direct point of the question. | |
