FMCW radar design files

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.

fmcw2's Issues

Bill of Materials?

I'm interested in re-creating this project, but I can't seem to find a list of all electronic components soldered to the PCBs. This information would be very helpful.

Usable for implementing EQ Radio?

I noticed you blogged about measuring breathing & heart rate. (http://hforsten.com/heartbeat-detection-with-radar.html)

Do you think this design could be used to implement the system in this paper?

About processing with analysis.py

Hi Henrik,
I'd like to ask you about the analysis.py code, it requires to read a filename.sync in line 49, is this file a copy of the previous file read in line 27
(with changed name "filename.sync" or manual added extension ".sync")?

I tried to generate and verified data but had some trouble with this.
File C:\analysis.py, line 73, in <module> acc += syncs[i] IndexError: list index out of range

Thanks in advance!
