I found the following sentence in the datasheet of a FMCW module:

```
FMCW ramp is visible at the outputs caused by self-mixing effects, near objects and cover (RADOM).

```

My search results are flooded with information about the city Radom and the firearm. Is it something like a term for a collection of radar obstructing materials?

EDIT:

I see the suggestion RADOM standing for radome as both a comment and as answer. However, I wouldn't expect capitals if they mean radome. Is there any reference to these two being one and the same?

The context suggests RADOM being some kind of obstruction. As far as I know, radome polymers don't count as obstruction (that's why they're radome, invisible to radar).
