CCS/IWR1843BOOST: The cloud point question ( people counting lab)

Agate
Expert 1275 points
Part Number: IWR1843BOOST

Tool/software: Code Composer Studio

Dear TI 

                  The below diagram shows the cloud point range , how to wider this region ? 

                  It's effected by which  parameters ? Why some module the direction is different with the same code ?

    Hi Agate,

    That is a strange FOV, typically it would be centered around X = 0. In general, all of our EVMs have about 120 degrees of Azimuth FOV, with variable elevation FOV. What demo are you running, and what EVM are you using?

    Regards,

    Dear TI 

                   It's the same setting but the board it's a type of our design , Antenna will effect this FOV performance ?

                  Customer don't agree antenna  and IC in the same side we need to try more and different hardware to our customers .

    Hi Agate,

    The Antenna will effect the performance. Specifically, the layout effects the Angle of Arrival function - if you change the layout without changing AoA in software, you will get strange results like the ones above. Can you confirm that the Virtual Antenna pattern is the same as ISK?

    Regards,

    Dear TI 

                     Becuase we are focus on non-automotive market , every customer have their requirement  , especial  the hardware layout . 

                    So 100% the hardware layout will be changed , The AOA we are keep the demo setting becuase we don;t how to change with hardware 

                    Can help us how to change these setting. ? The virtual channel setting are follow ISK but AOA keep the same. 

                    Our Antenna Pattern is 90% the same with TI antenna performance and gain & bandwidth is large than TI

    Hi Agate,

    If the antenna layout is the same as the TI layout, the AOA algorithm will work, regardless of hardware or antenna gain. Which software are you running on device? Are you able to show the antenna layout?

    Regards,

    Justin

    Dear TI
            The antenna layout we have discussed .
            I don't know how to setting AOA part.
    　　
    　　show two layout for you to reference.
    Our customer side suggestion much configuration .
    now we are try run some type only but performance not good now.

    You are using 3D People Counting, correct? Do you have the antenna geometry configurations set properly for these as discussed in the other thread?

    Dear TI 

                We have use 3D people counting and HAVC . antenna geometry we understand how to setting , you have teach us but AOA we don't know how to fit antenna .
