Modifying an HB100 X Band Doppler Radar Module for FMCW Ranging Measurements
Look at very old PCM (Pulse Code Modulation) used freq hopping to avoid detection and jamming. 60's era satellites and spec ops ground comm.
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.
Details please?
