There’s no doubt that radar has played a large role in the study of the UFO phenomenon. For decades, strange and mysterious craft have been recorded on radar-screens by personnel at numerous military facilities. But, we get further, though, here’s a bit of background on radar: As the people at
ExplainThatStuff! state: “An airplane’s radar is a bit like a torch that uses radio waves instead of light. The plane transmits an intermittent radar beam (so it sends a signal only part of the time) and, for the rest of the time, “listens” out for any reflections of that beam from nearby objects. If reflections are detected, the plane knows something is nearby—and it can use the time taken for the reflections to arrive to figure out how far away it is. In other words, radar is a bit like the echolocation system that “blind” bats use to see and fly in the dark.” With that said, now let’s take a look at some fascinating cases. In September 1952, NATO held a large-scale military exercise in the North Sea and English Channel. Its name: Operation Mainbrace.
