Under the radar
“Under the radar” is an idiom that comes from military jargon, referring to aircraft flying at a low altitude to avoid detection by radar systems. In everyday language, this phrase means to operate discreetly or unnoticed, to go unnoticed by others intentionally. When someone or something is “under the radar,” it implies that they are not attracting attention or scrutiny.
This idiom suggests a sense of stealth, secrecy, or flying under the radar to avoid unwanted attention or detection. It can be used to describe actions, behaviors, or individuals who are intentionally keeping a low profile or staying out of the spotlight. For example, a business might launch a new product quietly to test the market under the radar before a full-scale release. In personal contexts, being “under the radar” could mean working on a project quietly without seeking recognition or operating behind the scenes to achieve a goal without drawing attention. It can also imply staying out of trouble or avoiding notice by authorities or others.
