IWR6843ISK-ODS: Some issues about the people tracking design document

Hi,

If you only use 4 virtual antennas to estimate elevation, you will lose out on SNR gains from using all the available information. If you use our existing code, it does this by default, so there is no need to modify.

hello，

The elevation estimation method I found is based on calculating the phase difference of two rows of virtual antennas such as：

or  

What is the principle and basis for using all 12 antennas? Is there any theoretical data?

Hi,

Omitting additional antennas from the chain would result in a loss of SNR. This is why it is advantageous to use all antennas.

Hello,

I need the specific process and mathematical theory for angle estimation using 12 virtual antennas rather than its benefits, as using all virtual antennas is not convincing.
