Hello,
According to the manual, the IWR6843ISK board has a field of view of +/- 15 degrees, 30 degrees in total. It also says that the Elevation Angular Resolution 58 degrees is. As per my understanding, this elevation angular resolution means that two distinct objects can be distinguished if they are 58 degrees apart relative to the antenna. It is unclear to me how to interpret this. To me it seems that only one object can be measured vertically because 58 degrees is bigger than the total FoV of 30 degrees.
This, however, contradicts with the video that I saw at this video:
In this video, the angular resolution seems to be much smaller, since each detected object seems to be measured pretty accurately when they display the point cloud (at 0:55 seconds).
Can someone clarify to me how the Elevation Angular Resolution can be bigger than the Field of View? And then how is it possible that the Robot in the video seems to detect heights of objects pretty accurately? I am new to mmWave and looking for possibilities to build an autonomous robot using mmWave for Simultaneous Localization and Mapping (SLAM). Thank you in advance.
