Hello,
my customer have AWR1642 radar sensor. they in Optimal working on 2 projects related to sensing capabilities in biomedical industry.
they need sensor how can measure "raw" data – amplitude, phase and frequency of operation.
they need very clear instructions how to do it.
also they want to know about solution above 100GHz. hope someone could advice.
best regards,
shahaf
Hello Zalman,
Your picture is not showing up, however I have updated my above post with some better data. The data I posted before did not look correct to me when I tried to plot it. What you should see if you plot the updated data are the following two plots:
Where the first plot is simply the raw real and imaginary ADC data and the second plot is the 1D FFT which shows a peak for a single detected object roughly 1m away. If you zoom in on the first plot you can see the real (solid line) and imaginary (dotted line) parts of the raw ADC data more clearly. It should be a sine wave whose frequency is a function of the distance of the object.
In order to compute the
Amplitude of reflected wave as function of frequency
Phase of reflected wave as function of frequency
You would need to modify the code to make the computations using the obtained ADC data. In the code provided, the ADC data is stored in a two dimensional array called 'rad_in', where the first column contains the real part and the second column contains the imaginary part.
Regards,
Adrian
