Original question:

AWR2944EVM: AWR2944EVM

AWR2944EVM: AWR2944 EVM

Other Parts Discussed in Thread: AWR2944

Hi TI Community,

I'm currently working on an experiment using AWR2944 EVM aimed at identifying object distance from the radar and distinguishing between multiple objects while also calculating their respective distances and velocities. However, I find myself at a loss on how to start this experiment effectively.

Could someone provide guidance or resources to help me get started with this experiment?

Any advice, documentation references, or sample code snippets would be greatly appreciated. Thank you in advance for your assistance!

Best regards,
Bhavana

    Hi Bhavana,

    You can check the demo or example applications present in the radar toolbox to start with.

    Hi Shruti,

    Thank you for your response. I appreciate your suggestion to check the demo and example applications in the radar toolbox. However, after exploring these resources, I couldn't find any examples that specifically address my needs.

    I want to run an experiment using the AWR2944 EVM board. Let's assume there are two objects in the sensing region of the radar. My goal is to compute the distance of these objects from the radar and determine whether one is moving or stationary. To achieve this, I need access to the signal properties so that I can analyze the underlying signal characteristics. This includes understanding which signals help compute distance, distinguishing between stationary and moving objects, and identifying any changes in signal properties based on the shape of the objects.

    Since I don't have access to a DCA1000 EVM, I was wondering if it's possible to modify the source code of the mmWave demo visualizer for this experiment.

    I have read about the mmWave demo visualizer, but I'm unsure how to customize the code to meet my specific requirements. For example, I may need to adjust the frequency for data transmission and receiving beyond the default settings.

    If you have any insights on how to achieve this, I would be very grateful for your assistance.

    Thank you .

    regards,

    Bhavana

    Hi Bhavana, 

    without the DCA you cannot read the raw adc data, which is needed for your range, velocity computation.

    I would suggest you to go over the mmwave studio user guide to understand the post processing.
