Sausage radar. Simple doppler radar that fits into a sausage can. Named after "Wurstblinker" from the german movie Werner, as it also is meant to be mounted on a motorcycle as an alternative to the speedometer.
RSM2650 Radar movement alarm unit (this probably is an Innosent IPS-265)

1bitsy STM32F415 on a tiny breakout board

Used Simpson Voltmeter 5V as analog dial.

Generic powerbrick to 5V
- e.g. TI TPSM84205
A JTAG debugger.
- e.g. Black Magic Probe
Only arm-none-eabi-gcc

FMCW / Range Doppler (minor hardware change, complex firmware changes)
The current antenna module (RSM2650) can be replaced with a module that supports a tuning voltage. Then, FMCW and Range-Doppler could be done. The tuning voltage could be supplied with the STM32 DAC, which already has some support code in the git history.
-
Improved signal quality and range (complex hardware changes)
The analog frontend currently is a simple opamp amplifier with decoupling and biasing. Options are to increase the amplification, pick better opamps or dedicated LNAs. Automatic gain might me an option with that.
-
USB waveform output (simple firmware changes)
Output both I and Q as a data stream via USB, so a connected computer can use them.
Clone first: git clone --recursive https://github.com/dpiegdon/wurstradar.git
Then build libopencm3: cd wurstradar/libopencm3 && make
Then build the firmware: cd ../src && make
-
you can set the measurement angle and its proper doppler frequency via
commandline: make DOPPLER_HZ_PER_POINT1_KPH=314 MEASUREMENT_DEGREE=45
Flash it to the 1bitsy. E.g. with a Black Magic Probe.
