I have been using the mmWave IWR6843ISK-ODS radar sensor along with the 3D People Counting lab in the Industrial Toolbox. I know that the configuration file has set the maxNumPoints to 800, but when using the sensor, I only ever get a maximum of ~70 points, even with multiple people. I am trying to fine-tune the sensor to be more sensitive and detect more points. It appears that I can achieve this result by configuring the detection layer parameters to get more motion sensitivity (referring to this tuning guide).
In section 4.1 of the tuning guide, it defines velocity resolution as being "the minimum radial velocity difference between two objects for the radar to detect them as separate objects in the Doppler domain." To me, this means that if the velocity resolution is low, meaning that there is a smaller minimum radial velocity difference required between two objects, then the sensor will be more sensitive to motion. And vice versa.
However, in section 4.3 of the tuning guide, it says that:
"As discussed in Section 2, to successfully leave the signals scattered from the moving objects after the static clutter removal step, a high-velocity resolution is needed to improve the motion sensitivity. On the other hand, when the velocity resolution is increased, the processing chain becomes more sensitive to undesirable motion artifacts such as sensor vibration."
This makes it seem that if the velocity resolution is high, meaning that there is a larger minimum radial velocity difference required between two objects, then the sensor will be more sensitive to motion.
Am I missing something here?
