IWR6843ISK-ODS: How to configure TDM

Part Number: IWR6843ISK-ODS

Hi,

How to configure TDM with IWR6843ISK-ODS+DCA1000?

1.How to configure TDM into three transmitting and four receiving, a total of 12 virtual receiving antennas?

2. If it is configured as 12 groups of receiving antennas, can it be divided into 8 groups of horizontal antennas to analyze the horizontal angle and 8 groups of vertical antennas to analyze the elevation angle?

3. If 1 and 2 are wrong or cannot be achieved, how can I obtain the original data through DCA1000, which can resolve to both the azimuth angle and the elevation angle?

    Hello,

    Please read the following resource:

    MIMO Radar:

    https://www.ti.com/lit/an/swra554a/swra554a.pdf

    I would focus on everything except the BPM section unless you are interested. This will explain the theory behind antenna placement and how that goes into virtual antennas arrays. Additionally, this resource details how profile, frame, and chirp configurations of the device play a role in implementing TDM MIMO.

    If you want to capture raw ADC data via the DCA1000 using MMWAVE Stuidio then please refer to the following resource:
