📡 Surveillance Radar Lab: Range Equation, Doppler, Horizon and Clutter

A generic air-traffic and weather radar on a hill, with rotating antennas, a control cabin, six airliners and a rain front on a 240 km height map: range equation, pulse timing and range ambiguity, Doppler with MTI blind speeds, 4/3-earth radar horizon, terrain masking, ground clutter and rain attenuation on a live PPI display.
