Understanding the Idiom
Under the radar is an idiom that means something or someone is not getting attention or going unnoticed.
It is often used to describe a situation where something is happening without being detected or observed.
The idiom can be used in both literal and figurative contexts.
Origins and History
The phrase “under the radar” originated after World War II when radar technology was first used to detect incoming fighter and bomber jets.
Due to interference with radio waves by the ground, planes that flew low could not be detected by radar.
So those planes that could not be detected were said to have flown under the radar.
Over time, the phrase evolved to refer to anything that is happening without being noticed.
The literal meaning of the idiom refers to something that is physically under the radar, such as an object or a person.
For example, “The small boat went under the radar of the larger ship.” In contrast, the figurative meaning of the idiom refers to something that is not getting attention or going unnoticed.
For example, “The new restaurant opened quietly and went under the radar of most food critics.”
