OED has "under the radar" grouped with other figurative expressions that

I am a bit puzzled by the bracketed citation. It's not particularly
figurative and it does not point to the original usage, which goes back /at
least/ to the 1960s, although many of the ones I found all refer to "under
the radar screen". I suppose it combines the literal base for the expression
as a simile.

A possibly earlier entry is more ambiguous date-wise--it's an 1983 re-print
of a 1953 military publication.

But another pops up before 1981.

I'd be shocked if Tom Wolfe were responsible for this migration. But the
meaning here is not quite literal. The way it's used here, "under the radar"
means to avoid being detected and targeted by Surface-to-Air-Missiles
(SAMs)--not literally the same expression as "under the radar screen", but
still close. Internal reference in the story is 1967. But in all cases the
meaning is already figurative--it means "undetected".
There is an oddity here. The expression "below the radar" likely comes from
"below the radar beam" or "below the radar horizon"--both evident since the
invention of the radar. But there is no evidence of anything other than
"under the radar /screen/" over the same period. It was never literal! On
the other hand, "on the radar" nearly always refers to a screen, display or
picture--and nearly all pre-1980 cites use it that way, whether for
air-traffic radar, naval radar or police radar. The more contemporary
expression might be "[does not] register on the radar".
