📡 Radar Beam Height, Earth Curvature, Terrain Blockage and the Range-Velocity Dilemma PPI Lab

Aim a weather-radar dish over synthetic terrain: the 4/3-Earth beam climbs above low storm layers, a ridge blocks part of the beam, and the PRF trades unambiguous range against Nyquist velocity. Watch the PPI picture show overshooting, shadows, range-folded ghosts and aliased winds, next to a range-height diagram. Blender-modelled radar site and terrain.
