AWR6843AOP: Mobile Tracker to use with AWR6843AOP

EMRE ÖZDEMİR

Part Number: AWR6843AOP
Other Parts Discussed in Thread: AWR6843ISK

Hello All,

We have AWR6843AOP custom design board.Mobile tracker demo is appropriate for our customers request.

How can I import Mobile Tracker from AWR6843ISK to AWR6843AOP.

I know that I need to change Antenna Patern and Phase.

I coundn't find this information in Mobile Tracker Demo code.

But still , in mmwdemo_rfparser.c file there is this code 

#ifdef SUBSYS_MSS

MmwDemo_RFParserHwAttr MmwDemo_RFParserHwCfg =
{
SOC_ADCBUF_SIZE,
0x2,
0x5
};

And 

0x2 is elevTxAntMask

0x5 is azimTxAntMask

I think I need to change these values for AOP.

Plese give me a guide for configure the code for AWR6843AOP.

Thanks 

EMRE

    Hello EMRE,

    I have given the process in which one can get Mobile Tracker/Robotics code working with AOP in the thread here: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1135403/awr6843aop-6843aop-radar-sensor-robotics-application/4224627?tisearch=e2e-sitesearch&keymatch=%20user%3A519338#4224627

    You have to start from People Counting rather than Out of Box Demo (which is what Mobile Tracker is built from). Doing diffs between OOB and Mobile Tracker projects and then copying those diffs into People Counting source. I will confirm you are correct about changing the antenna pattern and that will happen in the configuration (cfg) file portion.

    Hi Pedrhom Nafisi

    Thanks for help.I checked the linked question.

    I am new on this radar sensor so I need more clarification.

    Mobile Tracker and People counting example use different object Detection algorithm in the DPM side.

    Mobile Tracker use     objectdetectionandtracking

    People counting use   cupon3D

    I think I need to change object Detection algorithm on people counting and remove "MmwDemo_trackerDPUTask" from it for mss side and change Detection algorithm on DSS side.

    But antenna patern is used in Capon2DBF if I change detection algorthim than I lose antenna patern information.

    Can you give me a guide please.

    Thanks.Best Regards.

    EMRE.

    Hello EMRE,

    You are correct with the detection algorithms being different between People Counting, and Mobile Tracker. I want to add that Mobile Tracker is built off of Out of Box demo (OOB). People Counting uses Capon3D and OOB uses Bartlett. The tracker library and code is mostly independent from the detection layer, but the problem is where the detection layer is done in OOB (MSS) and people counting (DSS). 6843AOP needs to have detection layer on DSS due to core design choices, so the current model of Mobile Tracker/OOB does not work.

    While you can move the detection layer around, because the tracking layer is smaller it is much easier to move that instead and I highly recommend implementing it this way. For this reason, I suggested doing a diff between OOB and Mobile Tracker. Note that Mobile Tracker is literally OOB with tracker added and no other changes. So doing a diff between these two projects you will see exactly what additions are made to add the tracker. Once you note the files/code added to OOB for tracking, you copy them over to the People Counting project. This will ultimately give you detection + tracking on 6843AOP.

    Best Regards,
