AWR1843BOOST: How to calibrate the AWR1843BOOST board and increase the radiated power？

Part Number: AWR1843BOOST

Tool/software:

hi, engineers

I want to know how to calibrate the AWR1843boost board and increase the radiated power of the radar board?

I downloaded TI's pre-bulit bin file to the radar board, as shown below. But it doesn't seem to be radiating far enough,

because it is only about 5 or 6 meters far , beyond the distance, there is no any echo of mmwave radar .

 so I want to calibrate the board and increase the performance of the awr1843boost board.

Regards,

Wembanyama

    Hi,

    Please share with us more information about your use case.

    The radar sensor is configurable. With the mmWave SDK oob demo you should be able to detect a car at a range ~40m.

    For larger ranges you should consider using the MRR demo provided in the TI Radar Toolbox

    Thank you

    hi, so sorry to bother you. I use AWR1843boost radar board and download the prebuilt bin file in the radar board by using mmwave Studio2.1.1.0. 

    I would like to know the radar profile files in the picture below , what mode does it use? What is the radar of AWR1843boost max range?

    In fact, I want to use the oob demo and MRR demo you suggested to achieve radar target ranging and DOA measurement, so as to find out the performance difference between this prebuilt bin file and oob demo and MRR demo.

    Regards,

    Wembanyama

    hello, 

    in the above picture it looks like you are using mmwavestudio, which is used to capture raw data. It is not used to run the out of box demo/processing chain. If you want to the run the OOB, it demo can be found here 

    C:\ti\mmwave_sdk_03_06_01_00-LTS\packages\ti\demo\xwr18xx\mmw

    The instructions to run it can be found in the user guide. The user guide also contains how to edit and change the profiles configuration to get a better range

    C:\ti\mmwave_sdk_03_06_01_00-LTS\docs

    If you want to continue using mmwavestudio to capture raw data you can change the profile configuration in the lua script. If this is your first time dealing with TI radars I recommend you use the out of box demo. You can use the sensing estimators(link below) second tab to configure the chirp to get the max distance you wish to see 

    https://dev.ti.com/gallery/view/mmwave/mmWaveSensingEstimator/ver/2.4.0/

    The following document explains the relation between chirp configuration parameters and physical chirp characteristics
