Bug #1 — Range calibration for Raw IQ Replay:
- Add WaveformConfig dataclass (models.py) with FMCW waveform params
(fs, BW, T_chirp, fc) and methods to compute range/velocity resolution
- Add waveform parameter spinboxes to playback controls (dashboard.py)
- Auto-parse waveform params from ADI phaser filename convention
- Create replay-specific RadarSettings with correct calibration instead
of using FPGA defaults (781.25 m/bin → 0.334 m/bin for ADI phaser)
- Add 4 unit tests validating WaveformConfig math
Bug #2 — Demo + radar mutual exclusion:
- _start_demo() now refuses if radar is running (_running=True)
- _start_radar() stops demo first if _demo_mode is active
- Demo buttons disabled while radar/replay is running, re-enabled on stop
Bug #3 — Refactor adi_agc_analysis.py:
- Remove 60+ lines of duplicated AGC functions (signed_to_encoding,
encoding_to_signed, clamp_gain, apply_gain_shift)
- Import from v7.agc_sim canonical implementation
- Rewrite simulate_agc() to use process_agc_frame() in a loop
- Rewrite process_frame_rd() to use quantize_iq() from agc_sim
- workers.py: Only emit playbackStateChanged on state transitions to
prevent stale 'playing' signal from overwriting pause button text
- dashboard.py: Force C locale on all QDoubleSpinBox instances so
comma-decimal locales don't break numeric input; add missing
'Saturation' legend label to AGC chart
- map_widget.py: Enable LocalContentCanAccessRemoteUrls and set HTTP
base URL so Leaflet CDN tiles/scripts load correctly in QtWebEngine
State machine fixes:
1. Raw IQ replay EOF now calls _stop_radar() to fully restore UI
2. Worker thread finished signal triggers UI recovery on crash/exit
3. _stop_radar() stops demo simulator to prevent cross-mode interference
4. _stop_demo() correctly identifies Mock mode via combo text
5. Demo start no longer clobbers status bar when acquisition is running
6. _stop_radar() resets playback button text, frame counter, file label
7. _start_raw_iq_replay() error path cleans up stale controller/worker
8. _refresh_gui() preserves Raw IQ paused status instead of overwriting
Map/location:
- RawIQReplayWorker now receives _radar_position (GPSData ref) so
targets get real lat/lon projected from the virtual radar position
- Added heading control to Map tab sidebar (0-360 deg, wrapping)
- Manual lat/lon/heading changes in Map tab apply to replay targets
Ruff clean, 120/120 tests pass.
Add a 4th connection mode to the V7 dashboard that loads raw complex IQ
captures (.npy) and runs the full FPGA signal processing chain in software:
quantize → AGC → Range FFT → Doppler FFT → MTI → DC notch → CFAR.
Implementation (7 steps):
- v7/agc_sim.py: bit-accurate AGC runtime extracted from adi_agc_analysis.py
- v7/processing.py: RawIQFrameProcessor (full signal chain) + shared
extract_targets_from_frame() for bin-to-physical conversion
- v7/raw_iq_replay.py: RawIQReplayController with thread-safe playback
state machine (play/pause/stop/step/seek/loop/FPS)
- v7/workers.py: RawIQReplayWorker (QThread) emitting same signals as
RadarDataWorker + playback state/index signals
- v7/dashboard.py: mode combo entry, playback controls UI, dynamic
RangeDopplerCanvas that adapts to any frame size
Bug fixes included:
- RangeDopplerCanvas no longer hardcodes 64x32; resizes dynamically
- Doppler centre bin uses n_doppler//2 instead of hardcoded 16
- Shared target extraction eliminates duplicate code between workers
Ruff clean, 120/120 tests pass.
v7/__init__.py: wrap workers/map_widget/dashboard imports in try/except
so CI runners without PyQt6 can still test models, processing, hardware.
test_v7.py: skip TestPolarToGeographic when PyQt6 unavailable, split
TestV7Init.test_key_exports into core vs PyQt6-dependent assertions.
Resolve all 374 ruff errors across 36 Python files (E501, E702, E722,
E741, F821, F841, invalid-syntax) bringing `ruff check .` to zero
errors repo-wide with line-length=100.
Rewrite CI workflow to use uv for dependency management, whole-repo
`ruff check .`, py_compile syntax gate, and merged python-tests job.
Add pyproject.toml with ruff config and uv dependency groups.
