under the radar

Describing an action that cannot be detected. The term comes from aviation during World War II, where a plane is flying too low to be detected by the enemy’s radar. It soon was transferred to other situations, as in “I don’t want anyone to know I’m looking for another job, so keep my applications under the radar.” John Lescroart used it in A Plague of Secrets (2010), “Now I know . . . it hasn’t been the subject of much police concern so far . . . So up to now you’re all under the radar.”

Radar beams (and radio signals) generally travel in a straight, line-of-sight path, so the information available from radar waves is limited by what they can "see." The top three issues causing radar information gaps are: 1) the distance between radars (typically -215 miles/345 km in the western U.S.); 2) mountains and other terrain blocking radar beams; and 3) the Earth's curvature, which limits the ability of long-range radar to observe the lowest parts of the atmosphere, that which is at less than 10,000 feet and distances greater than 108 miles/175 km.
