Morphology

radiation + pattern

The meaning is compositionally transparent: 'radiation' denotes emitted energy and 'pattern' denotes a distribution or representation, so a B1 learner who knows both words can infer that a 'radiation pattern' refers to how radiation is distributed or represented (often graphically). While the full technical/mathematical details may be specialist, the core idea is directly derivable from the constituents.

Etymology

The noun radiation pattern comes from the picture of an antenna like a lamp that sends out radiation more in some directions and less in others, and when you draw this on a graph you see a clear pattern of strong and weak spots, so the phrase means 'how the signal is stronger or weaker in each direction'.
