Morphology
The meaning — a beacon related to or operating with radar signals — is directly derivable from combining 'radar' (radio-based detection) and 'beacon' (navigational signal transmitter). This is a straightforward noun–noun modification following normal composition patterns and is cross-linguistically transparent, so a B1 learner who knows both constituents would likely infer the MWE's function.
Etymology
Radar beacon is like a small answering lighthouse for radar: the radar sends a signal and the beacon replies with a special code, so pilots or sailors can 'find their position'.
