Morphology

fly + under + the + radar

The phrase maps a literal scenario (an aircraft flying below a radar’s detection) onto the abstract idea of avoiding notice, so the constituent meanings (fly + under + radar) do give a plausible clue. However, the metaphor requires world knowledge of what radar does and a figurative inference that may not be immediately obvious to an average B1 learner, so it is not fully compositional or predictable.

Etymology

The idiom fly under the radar may come from the image of an airplane that flies so low it goes under a ship's radar and is not seen. That's why the phrase means 'to avoid being noticed'.
