Doppler Analysis

To obtain a plot, do the following:

1. In the results tree, select Power (MS) or Power. These are the power received by the receiver antenna and the power received by a hypothetical isotropic antenna, respectively.
2. Select the time step of interest (if it was a time-variant simulation).
3. Click Display > Doppler Analysis and select one of the following:
   • Doppler Shift
     • Hover the cursor over the result pixel of interest for Doppler shift.

       
       

       

       
       Figure 1. A graph showing for all contributing rays the Doppler shift along the horizontal axis and the power along the vertical axis.

   • Doppler Shift (3D)
     • Click on the pixel of interest. In an automotive radar simulation, there is often just one result pixel, located at the radar position.
       Tip: Zoom in if needed to view the result pixel.

Plot radar results as a heat map, with range and relative velocity along the axes and signal strengths as colors. To obtain a Doppler Heat Map, do the following:

1. In the results tree, select Power (MS) or Power. These are the power received by the receiver antenna and the power received by a hypothetical isotropic antenna, respectively.
2. Click Display > Doppler Heat Map.
3. Click on the radar pixel to generate the heat map.
4. [Optional] Activate/deactivate the legend on the plot by right-clicking on the plot and click Settings > Layout and select/clear the Display Legend check box.
