AWR2944EVM: The questions of the computation about the azimuth and elevation angles

AWR2944: How could I do range, speed, DOA estimation using raw data from AWR2944 in DDMA mode?

Part Number: AWR2944

Hi, we would like to customize the antenna 4TX 4RX using AWR2944 (more power, and more LNA), we would like to capture RAW LVDS data from AWR2944 in DDMA mode. How could we implement our own range, speed, DOA estimation algorithm using the raw data (in DDMA mode)? is thre any document on this?

    Hi,

    Our OOB demo already supports raw data capture over LVDS in DDMA mode. In addition, the datapath/ folder of the SDK contains both TDM and DDM chains. You can look at the doxygen documentation of the DDM chain components to get a better idea of how DDMA is implemented. Also, the high end corner radar reference design contains a brief overview of the theory of DDMA.

    Thank you. Where could I get OOB (what is OOB stands for?) demo and the doxygen files for DDMA mode? Is this demo support customized Rx, Tx antenna locations?

    Hi,

    OOB stands for out of box demo. When you download the mmWave MCU+ SDK (link), you will be able to find the OOB demo at <MMWAVE_MCU+_SDK_LOC>/ti/demo/awr294x/mmw.

    Reading the user guide of the SDK will help with the usage of the demo.

    The OOB demo utilizes the SDK datapath components (<MMWAVE_MCU+_SDK_LOC>/ti/datapath/). There are multiple components in the datapath. Each of these and the demo has a docs/doxygen folder, which contains an index.html file, which is the entry point to the doxygen documentation. These go into implementation details of the various modules.

    This demo does not however, have configurability for the RX, TX positioning.

    Regards,
