RTOS/AWR1642: FOV

ks prasad
Expert 1255 points
Part Number: AWR1642

Tool/software: TI-RTOS

Hi,

please find inline queries.

Could you please elaborate what you mean by "FOV(Field of view) of AWR1642 boost to be 50 degrees and 15 degrees for short range coverage(80m)."

ans:we want to maintain short range that is 80m but want to limit field of view to be 50 degrees.

Will you develop your custom software or will you be re-using some of the software?

ans: we are using SRR demo code provided by ti on AWR1642 BOOST but want to do software changes to meet above requirement.

Let's assume you will use the OOB SDK demo.

The demo sends (x,y) detected point information for +/-60deg to the host through uart.

It is possible for the host gui to limit display of points only in smaller FOV such as +/-50deg or +/-30deg 

ans: yes it is possible in gui.But we want to do it in radar operational level.The reason is,instead of uart,if other interfaces are connected(CAN ..etc) ,Objects beyond 50 deg FOV are still coming in CAN logs. Main objective is to decrease FOV (still maintaing 80m range and without HARDWARE change i.e still using AWR1642BOOST).

Thanks,
K Subrahmaniam

    Hi,

    Instead of GUI it will be possible to discard the information outside the FOV in the SW.

    Thank you

    Thank You Ceasar,
    Please can you guide me to achieve above requirement (which part of the code in SRR need to be modified to meet above requirement) and send object information within FOV only over interfaces(UART,CAN etc).

    Thanks,
    K Subrahmaniam

    Hi,

    In order to achieve this you would need to have a very good understanding of the SRR demo.

    Please search the forum about how to set up breakpoints in the code. This will help you go through the code and understand the details.

    You will have to modify the angle estimation of the location of detected object. In the SRR demo the angle estimation is similar to the OOB demo. Please refer to the OOB demo documentation since it is more detailed.

    It is located in

    C:\ti\mmwave_sdk_02_00_00_03\packages\ti\demo\xwr16xx\mmw\docs

    Please review section "Data Path - (X,Y) Estimation"

    I will close this thread. If you have new specific questions please start a new thread

    thank you
    Cesar
