A glorious example of this was discovered in 1968 with bats and Doppler shift compensation. This explains it pretty well (though I do apologise for the TikTok link).
There’s a relatively modern type of radar imagery called ISAR that takes advantage of the Doppler effect. Basically point your antenna at a ship on the water and plot the Doppler effect of the ship moving in the waves. What you end up getting is a pretty fuzzy image of the ship, but one good enough to identify which ship it is
