Morphology

3D + radar

The meaning is directly compositional: '3D' (three-dimensional) qualifies 'radar' (a detection system), so a B1 learner who knows both terms can infer a radar that provides three-dimensional information such as altitude, azimuth, and distance. This ADJ+NOUN pattern is straightforward and cross-linguistically common, making the MWE transparent to learners.

Etymology

3D radar combines 3D, meaning three directions: left-right, near-far, and up-down, with radar, a device that finds objects. Because it gives 'height' as well as direction and distance, the name helps you remember it shows where something is in space.
