3D- Chart: 
in 3D-view you can see the history of data, 
with the z-axis being the time line, so older 
values move to the back (higher z-values). 
X and Y like in 2D mode. 
 

 

Phasemarkers:  
as an extra option you can select to display 
phase markers on each recognized target. 
These markers show the phase angle of the 
detected target. The phase angle is very 
sensitive to slight changes of the target 
distance within one range bin. It can be used 
to display relative motion in the µm range. 

 

3.4  Status field and Target list: 

 

Statusfield: 
distance  in:  [mm,cm,  bin]  the  format  which  the  sensor 
specifies in the statusframe. 
accuracy:  the  width  of  one  range  bin  of  the  sensor.  It  is 
calculated using the following formula: 

 

 

 

 

 

 

update  rate:  calculated  from  the  TSLM-value  („Time  since 
last measurement“) which the sensor sends in milliseconds in 
the statusframe 
gain: gain setting of the baseband amplifier in dB  
bandwidth: the chirp bandwith  
 
Target list: 
The  target  list  is  ordered  by  distance.  With  every  new 
measurement having the CFAR operator enabled, the target
