AWR1843BOOST: Meaning of radial velocity

Hi Hiroyuki-san,

Radial velocity can be defined as the change in position of an object in motion over time in a non-linear direction respective to the perception of the radar. In a 2D plane the motion of the object can be defined as |Vr| = |Vx| + |Vy| where Vr is the radial velocity component, stemming as a result of the motion of the object with velocities Vx along the X-axis and Vy along the Y-axis.  

Essentially, the velocity of an object determined by the doppler processing of radar signals will be the radial velocity component by nature.

The max unambiguous velocity is the maximum extent of velocity that can be measured by the sensor without any ambiguity. Eg : if 10m/s is the max unambiguous velocity, it means that the radar can measure velocities spanning from 0m/s to 10m/s.
