In AWR1642 configure, the range of Doppler index set as 128, means -64 to +64 (And it supports -64*0.5 m/s to +64*0.5 m/s).
Thus, the maximum relative velocity to support will be -115.2 km/h to +115.2 km/h. Doppler with negative '-' means approaching, positive '+' means away...
The application what we use is for '"BSD" ADAS function, and we only take care of approaching obstacle.
We found the case that once the driver drive too fast which over 130 km/h, the reported Doppler index changes from positive '+' to "-" for the vehicle or fence away from me.
In such case, we lock the vehicle or fence to warn the driver might be in danger.
It seems the relative velocity is out of +115.2 km/h and it overflow (phase?), then becomes to minus relative velocity.
How should we do with such case?
Many thanks.
