Rooftop and ground-level radar arrays guiding autonomous eVTOL landing gear into tight urban vertipad touchdown slots.
Vertipads embed 140 GHz frequency-modulated continuous-wave (FMCW) radar transceivers. The system tracks descending landing gear with 5-millimeter accuracy, guiding autonomous craft through torrential rain and blizzard conditions.
High-speed Doppler scans monitor chaotic aerodynamic downdrafts reflected from the vertipad deck, commanding flight control computers to compensate for ground-effect air cushions before touchdown.
