FMCW radar hardware, firmware and processing software.

Folders:

hardware: KiCad hardware design files.

  • fmcw2: RF board.
  • fmcw2_mcu: Digital board.

firmware:

  • Firmware for LPC4320 microcontroller. Based on HackRF firmware.

host:

  • Host programs for recording data, programming firmware. Also from HackRF with small modifications.

processing:

  • fir: Resamples, filters and repackages samples for other programs.
  • filter.py: Output FIR filter coefficients for fir C program.
  • analysis.py: Various analyses about the recorded data.
  • sar_bicycle.py: Pre-processing of raw data.
  • sar_process.py: Focus raw data to SAR image.
  • sar_autofocus.py: Simple minimum entropy autofocusing of SAR image.

SAR focusing program is loosely based on Matlab program by Gregory L. Charvat and it also includes some functions from RITSAR.
