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
Further plans and ideas
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.
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
make DOPPLER_HZ_PER_POINT1_KPH=314 MEASUREMENT_DEGREE=45
Flash it to the 1bitsy. E.g. with a Black Magic Probe.
