Hi,
I have a question regarding the Vital Signs Demo.
As I understand, the Vital Signs demo uses a demo profile of 1Tx and 1Rx, with frame rate of 20 fps and 2 chirps per profile ("profile_2d_VitalSigns_20fps.cfg").
Theoretically, if I look at the phase of the returning signal from an oscillating object (such as pendulum, or Chest moving, in some specific range bin in the slow time), I should see the phase
signal (after wrapping) oscillating at the same frequency, this is of course when the sampling of the phase occurs in an equally spaced time intervals.
My question is- in this profile we have 2 chirps for in 1 frame, where the frame rate is 20 fps. Are the chirps transmitted 25 [ms] apart from each other? or, that they are transmitted one after
another very quick and then we have almost 50 [ms] of no data?
It will give me better understanding of the raw data (I,Q) that I get in the CCS, using the vital signs profile .
Thanks,
Boaz
