Part Number: AWR1243

Hi team,

I have a customer is asking How to use manage profile/ manage chirp feature in radar studio?

Could you please give a step by step guide for using 4 different profile in one frame using manager profile feature?

Thanks.

Regards,

Wesley

    Hi Wesley,

    The manage profile feature and manage chirp feature in radar studio currently have a few bugs. It is recommended to not use them at this time - these will be fixed in a future release.


    You can achieve the same behavior by using LUA commands to configure multiple chirps and profiles.

    Steps to configure 4 different profiles in one frame:
    1) You need to first configure the 4 profiles individually or by using the LUA commands
    2) You should then configure as many chirps as you require in the frame. Each chirp or set of consecutive chirps is associated with a particular profile ID. You should program at least 4 chirps with different profile Ids.
    3) You can then configure the frame to include these chirps, and you should then have chirps with 4 different profiles in each frame.

    Hope this helps.

    Best Regards,
    Anand

    Hi,Anand.

    Besides using LUA command, can I do follow this to finish a complex frame with multi  profiles and chirps:

    1/ repeat step 1-4 in fig1 to fish multi  profiles and chirps

    2/ config 1-3 in fig 2 to finish a complex frame with subframe/burst/chirp

    Yes, you can follow this procedure if you want to use subframes.

    what does Loop Bk Sub Frame Id mean? When I config a complex frame in advFramecong, how can i config Loop Bk Sub Frame Id and need i config LoopBackEn=1?
    if I config Loop Bk Sub Frame Id =3 , what is the frame construction?
    Thank you.

    Hi,

    You would normally not need to use loopback subframes. Do you have some use-case that requires these?

    Best Regards,

    i do not have the use-case.
    actually i am trying to learn the step how to config a complex frame with subframe,burst
    During learning i am confuse some parameter meaning in the AdvFrameConfig , like Loop Bk Sub Frame Id

    Can you solve the problem below?

    Could you please post a specific chirp configuration requirement? We can then help you program the device accordingly.

    The procedure is exactly the same as the 2 pictures you posted earlier in this thread.

                                                                                                    fig3 a frame structure

                                                                                                                                                           fig4

    Sorry, i donot state clearly.

    My aim is to config a frame like fig3. I know i need to finish 2 setps as below. But i do not know the exact number i need to set.

    1/First config the chirps C1~C6 by step 1-4 according fig1 (I posted earlier in this thread)

    assume I config the id of chirp C1~C6 is 0~5, and the profile id =1.

    2/Next config advFramecong in fig4.

    what is number i need to set for every parameter in Frame Configuration and sub frame Configuration?

     

    Is this example a specific frame?

    You can use something like the attached image. Change the burst period and subframe period numbers as needed.

    Thanks a lot Anand!

    You treat the frame in fig3 as a frame with 3 burst and each frame has a burst.

    i also want to know can i treat the frame as only one subframe and the subframe has 3 bursts ( also the chirp c1~c6 ids are 0~5, profile id =1)? if i can, how to  set the very parameter in Frame Configuration and sub frame Configuration?

    Note that the configuration screenshot I shared shows an advanced frame consisting of 3 sub-frames, and each subframe has one burst of 4 chirps each. It achieves what you want in figure 3.

    Could you please draw a diagram similar to fig 3 showing what you want?

                                                                                                                                                                 Fig5 frame structure

                                                                                Fig6 frame config

    Here is what i want to say.

    As to fig5, a frame with only 1 subframe. the subframe has 6 burst. Each burst has 4 chirps.

    is Fig6 right ?

  • 0 in reply to rongjiang liu
    TI__Genius 14755 points
    Yes, this is correct. The settings in figure 6 will achieve the frame in fig 5.

    Note that you have a very high subframe period, it can be done with something like 240 ms plus inter-frame idle time.

    All the above example, does not involve (1)Loop Bk SubFrame Id and LoopBackEn (2) SubFrame Start Configuration: SubFrame Ena

    1/ I know LoopBackEn is used to use in monitoring environments and usually LoopBackEn=0.
    So does it mean : if LoopBackEn=0, Loop Bk SubFrame Id is invalid?
    2/ How can i set SubFrame Ena? Usually SubFrame Ena=1?
    If I set SubFrame Ena=0, what is the result?
