Morphology

drop + off + the + radar

The literal parts ('drop' + 'off' + 'radar') do provide a plausible clue — something falling 'off' a detection system — so a learner can infer the sense of becoming undetected or out of contact. However, using 'radar' metaphorically for attention/visibility is somewhat figurative and the phrasal pattern 'drop off the radar' as a fixed idiom may not be fully predictable without prior exposure, making it only partially transparent.

Etymology

Drop off the radar comes from the picture of planes on a radar screen: if a plane flew low or moved out of view it would disappear from the radar. So, to drop off the radar means to become 'unseen', out of contact, or forgotten.
