Morphology

three-dimensional + radar

The meaning is directly compositional: 'three-dimensional' specifies the spatial dimensionality and 'radar' names the detection system, so a learner who knows both words can infer it is radar that provides 3D positional information (altitude, azimuth, distance). This noun‑compound pattern is regular and cross‑linguistically common, making the expression immediately understandable to a B1 learner.

Etymology

Three-dimensional radar is named for the three kinds of information it gives: how high something is, how far away it is, and which direction it is in. Imagine a radar that tells you an object's up-and-down, near-or-far and left-or-right position, so it means a radar that gives the target's full '3D' location.
