Since the coffee can thing had already been done I challenged my self to extra low cost. Using an HB100, teensy 3.2 and ADAU1761 I've built a functioning FMCW ranging radar.
In order to implement a FMCW Radar it is necessary to modulate the frequency of the oscillator. As far as I can see the HB100's oscillator has fixed frequency. I am very interested how you managed to modulate the oscillator's frequency, because I want to make a similar project myself, but I can't figure out how to do it.
Hello Tim.
Great project.
What you did was very interesting.
I have a few questions if I do not hinder you?
With what frequency generator HB100 sweeping (hz- Khz) ?
How did you do the FFT analysis?
On what platform ?
Thanks
Anton
