RTOS/AWR1642: FOV

Part Number: AWR1642

Tool/software: TI-RTOS

Hi,

We have specific requirement on FOV(Field of view) of AWR1642 boost to be 50 degrees and 15 degrees for short range coverage(80m).

As we go through manuals and forums ,FOV is 60 degrees.Is it possible to achieve 15 degrees and 50 degrees of FOV with AWR1642boost hardware.

Could you clarify  is it software configurable (or) fixed for awr1642boost board.

Thanks and regards

  • Hi,

    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)."

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

    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

    Thank you

  • Thank You
    How do we get FOV of +/- 15 deg and +/-40 deg. Is it possible or not.
    Thank you and regards,

  • 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,

  • Hi 

    Thank you ,

    we can limit the display of points through GUI . It is Ok. 

    Is it possible to change the existing c code to get required FOV ( fractional values also) ? or it is dependent on Antenna characteristics? 

    If it is possible to get different  required FOVs  by changing the code, please tell me the which part of the code we should change .

    we require +/- 15 degree FOV , +/-40 degree and some fractional values also . I want to know whether it is possible to get it by modifying the existing  c code.

    Thanks and regards ,

  • Yes,

    It is possible to perform the same operation in the target instead of the host.

    After the angle computation is performed, the sw can perform the selection and discard the values which are not needed

    thank you
