AWR1843BOOST: Improved resolution

May

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

Hi Team,

Customer want to get a high-resolution point cloud from the AWR1843Boost radar. They would like to get at a distance of 3 to a maximum of 10 meters in the area of 70-100 points per 1 square meter. This is necessary to create the likeness of a video camera for a smoky environment. Customer would like to see the capabilities of mmwave radar.

I am seeing some thread that improving resolution can be done using algorithm.

Do we have any documentation or labs for such a task?

Thank you.

Regards,
May

    Hi May,

    I would recommend to look at TI-Rex which has lot of different application based on different usecases.

    From these you will find some of the application best fit with your requirement.

    Hi Jitendra,

    Just received update from customer, please see details below.

    Hello, I know about this repository and the lab "lab0014_obstacle_detection_aop" seems to be the most suitable, but I failed to make a point cloud larger than the file "ods_aop_config.cfg" allows. And another question is why does radar not show walls in all labs?

    Thank you.

    Regards,
    May

    Hi Jitendra,

    In this screenshot, the radar is located at a distance of 2 meters from the wall, and does not display it

    Thank you.

    Hi May,

    Regarding this query, please note that Obstacle Detection AOP lab is specifically designed to function with AWR1843 AoP EVM and not with AWR 1843BOOST EVM. The Antenna orientation and configuration is different for both the EVMs as the former has the antenna's integrated onto the chip while the latter has it embedded on the EVM board. So we believe that should be the reason as to why the customer is not observing accurate results (wall detection at 2m). 

    Please refer the Medium range radar lab the customer (present in the Automotive Toolbox) which is designed to function with the AWR1843BOOST EVM which should work well at customer end and give accurate results. From there on modifications can be made to the project for their desired configuration settings.

    Thanks,

    Pradipta.
