Radar
Two builds share the signal chain.
- AERIS-10N, about 3 km, 8×16 patch array.
- AERIS-10X, about 20 km, 32×16 dielectric-filled slotted waveguide, plus a 10 W QPA2962 stage on each of 16 amplifier boards.
The array steers elevation electronically over ±45°. Azimuth on the prototype is a stepper. Carrier is 10.5 GHz. The FPGA does chirp generation, pulse compression, Doppler, MTI, and CFAR. An STM32 sequences power, clocks, phase shifters, and the GPS/IMU.

Overwatch
From the repository root, install the environment once, then start the stack. The start script generates local auth secrets on the first run, builds the operator UI, starts Postgres, Auth, PostgREST, Kong, and Nginx, and restarts the simulation backend. The operator view is at http://127.0.0.1:54321. The demo password is written to simulation/deploy/supabase/.env, which stays uncommitted.
./scripts/setup_environment.sh
./scripts/start_stack.sh
A headless physics check, after the environment exists:
