Hi,

I found the antenna element separations in the manual shown below. are these correct for IWR6843AOP EVM? what is the separation between Tx1 &Rx3? where do we place the origin?

    Hi,

    You can measure on the device, but it's not really relevant for the angle estimation. Angle Estmioation technically assumes all the antennas are co-located (which they are if you consider the difference in scale between the detected objects and the antennas). You can estimate it to be the center of the IC if needed.

    Best,

    Nate
