Dear,
Please pardon my little understanding of the subject matter.
But I will like some clarification on specifying the max range and velocity (as well as their minimum resolutions) especially concerning very fine motions and vital sign detection.
In the demo concerning very fine motion detection, the configuration 68xx_fine_motion.cfg used for detecting major (arm movements), fine (typing) and very fine (breathing/heartbeats) motions and it was stated that this was made used because the "chirp configuration configures the mmWave sensor for very high velocity resolution and a maximum range of about 6 meters". The configuration file gave the following parameters:
maximum range: 6.4m; range resolution: 12.5cm; max velocity: 1.18m/s; velocity resolution: 0.04m/s
But then in same documentation of the very fine motion detection, reference was made to the Vital Signs demo and the configuration for this demo was specifically optimised for vital signs (a type of very fine motion). The configuration thereof translates to:
maximum range: 7.4m; range resolution: 4.6cm; max velocity: 9.7m/s; velocity resolution: 2.4m/s
Now my question is which of these configurations is the optimal for very fine motions and/or vital signs detection? Noting that it is required that fine motions have 'very high velocity resolution' but the velocity resolution for fine-motion.cfg of 0.04m/s is << 2.4m/s of vital-sign.cfg
2. When aiming to design configurations for fine motions especially vital signs, should I aim for high velocity resolution (of 2.4m/s or thereabout) or low velocity (of 0.04m/s)?
