What Does the Idiom Under the Radar Mean?

The idiom under the radar means to go unnoticed without attracting attention or detection, often in a subtle or inconspicuous manner.

Merriam-Webster defines under the radar as “not getting attention: unnoticed.” Similarly, the Cambridge Dictionary defines it as “ignored or not noticed much by people in general.”

This phrase conveys the idea that something is happening quietly or discreetly, away from public or official scrutiny. It can be applied to various contexts, such as actions, developments, or individuals who are not easily noticed or acknowledged.

What Is the Origin of the Idiom Under the Radar?

The idiom under the radar can be traced back to the aftermath of World War II. The war marked the initial use of radar technology to identify incoming aircraft.

This phrase was commonly used in recounting stories of wartime aircraft. In later wars, the term was extended to soldiers camouflaging themselves within the environment, effectively remaining under the radar.
