Database of radars
Overview of presented here radar sets
Certainly there are (or existed in history) much more radars in the world than those mentioned here.
However, I can only list those radars here, about which I have freely available material.
There is no sense to copy material from other sites (for example from Wikipedia) just to appears another historical radar in this list.
However, if you have freely available material on new modern radar sets, and the confidence to create an article about it, then I have no problem to publish this article here in addition. (This offer has been often used by various radar manufacturers.)
