- Bandwidth 500 MHz -> 20 MHz, sample rate 4 MHz -> 100 MHz (DDC output) - Range formula: deramped FMCW -> matched-filter c/(2*Fs)*decimation - Velocity formula: use PRI (167 us) and chirps_per_subframe (16) - Carrier frequency: 10.525 GHz -> 10.5 GHz per radar_scene.py - Range per bin: 4.8 m -> 24 m, max range: 307 m -> 1536 m - Fix simulator target spawn range to match new coverage (50-1400 m) - Remove dead BANDWIDTH constant, add SAMPLE_RATE to V65 Tk - All 174 tests pass, ruff clean
