Tool/software: Code Composer Studio
Hello,
I'm running the vitalSgns_lab, there some questions confused me:
1. which signal is performed 1D FFT,the IF signal or the signal received from the Rx antenna?
2. the item 'range-bin' means what?
3. why the maximum reflectivity target corresponding to the maximum phase of signl after range FFT?
THANK YOU
Hello,
I would suggest first taking a look at the following document that explains the basics of FMCW radar.
1. The FFT will be performed on the IF signal.
2. In simplest terms, the range-bin can be thought of as the range resolution. If we have a range resolution of 0.04m, then anything within 0.00m to 0.04m will fall into the same range bin.
3. I am not sure I understand the question. Could you please clarify?
Regards,
Adrian
