Radar. In 1935, on the 26th Febuary, the radio station at Daventry was used for the first-ever practical demonstration of radar, by its inventor Robert Watson-Watt, who used a radio receiver installed in a trailer to receive signals bounced off a metal-clad bomber flying through radio beam.

RADAR is an acronym for radio detection and ranging.
In a relationship stand point it means that you are trying to keep that relationship from leaking out to others. !z Flying under the radar means to fly an aircraft below the scan of a radar beam. The reason why, ther is a cut off in elevation angle that cuts off the radar beam before it intersects with the sea or land. When a radar beam is almost parallel top a flat surface that is also in the beam returns from a vertical can suffer from multi path effect that cause cancelations, and since the beam giver a bigger area with range the effect become greater with range. Radar engineers know this and build the elevation profile to be cosec beam-shape in such that the radar beam cut off just before an intersection with a flat surface like land or sea. Given this cut off this mean that the radar multipath effect does not occur and detection at altitudes higher then the cut off are not going to surfer from multi path, however in bean that there is a area under the radar beam where the radar is not sensitive to targets, where a aircraft can fly under the Radar. However this phrase has come to mean doing something without being detected.
