Visualisation of RADAR activity
- Patched ath5k driver reports PHY error details to userspace via debugfs.
- Python daemon on Linux collects details, sweeps frequency ranges on-demand, and reports details to any connected client over the network.
- .NET GUI visualises legitimate WiFi packets and RADAR errors over frequency/time, plots histograms of pulse width, RSSI distribution, time between pulses, and draws time-series graphic to help uncover repetition rate within a sample of pulses.
