Radar.Spawn(transform, lifetime) clones the "Target Template", names it "Target" and attaches a RadarTarget that self-destructs after lifetime. RadarTarget aims each frame toward camera->target (full 3D LookRotation), drives the point renderer's _BaseColor from a forward-bearing gradient (ahead/side/behind depth cue lost in the flat disc projection) via a MaterialPropertyBlock, and scales the point renderer transform by camera->target distance.
