CCS/IWR1443: confused about sensor selection

Part Number: IWR1443
Other Parts Discussed in Thread: IWR1642, IWR1843, IWR6843, IWR1642BOOST

Tool/software: Code Composer Studio

hello,

I'm interested in ti mm-wave sensors and I watched a lot of video tutorials provided by ti. But I have still the following doubts?

1) Can I use a single mm-wave sensor for vehicle detection, animal detection, etc? or Is there any extra boards required for my application such as DCA1000

2) I need to place a system inside the forest for elephant detection. Which device is suitable for that IWR1642 or IWR1443?

3) How can I customize the code? is there any tutorial is available for code customization and explanation?

    Hi, 

    Single mmwave sensor can be used to detect static or moving object.  It can be also used for target classification, such as separating a person or dog.  But so far, we did not have a demo for animal classification.    You will have to develop yourself.

    Regarding which device, things you need to think about:

    1) Do you need a lot of process MIPs to develop the software?

    2) Which RF frequency band you need, 60G vs. 77G

    3) what antenna pattern you will need, in terms of field of view, angle resolution in azimuth and elevation.

    I would suggest you to think about iwr6843 or iwr1843 depend on which RF frequency band you need.   It provides more computation power and more antenna to choose from.    In terms of software development.  You need to download mmwave SDK, and look though the users guide.  You can also download the mmwave toolbox http://dev.ti.com/tirex/explore/node?node=AJoMGA2ID9pCPWEKPi16wg__VLyFKFf__LATEST.  There are a lot of labs you can consider to choose one to start.   All the source code is provided for SDK demo and toolbox demo code.  

    We also provide some training session, and you can to be on-site to learn from our expert.

    Best,

    hello Zigang,

    I don't know which antenna pattern and RF band are suitable for my application. 

    My application is just to detect vehicles in the 200-meter line of sight range and the detection should be live.

    Animal detection is my second preference, how can I develop software that?

    HI, 

    If you are trying to detect an elephant, you will need to detect 3-Dimension point cloud (x, y, z). 

    But if you are trying to detect vehicle, they are almost all on the 0 elevation angle.  So you only need 2-dimension point cloud (x, y).   I would recommend iwr1642Boost board .   

    By the way, you can find the antenna information for different board at: http://dev.ti.com/tirex/explore/node?node=AKu-aTm5FIcxlwZJU1pLBw__VLyFKFf__LATEST

    Regarding software development for animal detection,  we do not have an exact answer.  You can take a look at following lab: http://dev.ti.com/tirex/explore/node?node=AC63JY6F3gmrVCyLfpS.GQ__VLyFKFf__LATEST, which including classify moving objects as human or non-human when observing a mix of humans and moving fans, blinds, and curtains in an indoor scene.   But as I said, we do not have a lab yet for animal classification.    For general software development, you should start with reading through the user's guide and document in SDK (software development kit), it can be downloaded at: http://www.ti.com/tool/MMWAVE-SDK.   After that, if you have a detailed question, you can submit a separate e2e ticket. 

    Best,

    hi zigang,

    I need to detect people in a zone (Zone occupancy detection), I found http://dev.ti.com/tirex/explore/node?node=AOejQLXYplytU0fW5b-lbA__VLyFKFf__LATEST by using iwr14XX. 

    From the lab ( http://dev.ti.com/tirex/explore/node?node=AOejQLXYplytU0fW5b-lbA__VLyFKFf__LATEST  )  I found that the max range is 10 m and the angle is 180 degree. But I don't want a 180 degree angle,

    less than 60 degree angle is fine for my application but I need at least 70 meter detection range.

    Is it possible to increase the range by reducing the angle? or is there any other ways to increase the range?

    If I'm using IWR1642 boost, or 6843ISK What will be the maximum range with 40 degree angle?

    HI, 

    Usually, you can trade-off antenna gain vs field-of-view with a new antenna design.  With a fixed antenna design,  you will not have much choice.   But you also consider TX beam-forming to further increase the detectable range, which we will have a demo early next year.  It is demo on IWR6843, which will give you a max range of 100m for people detection.   You can come back to check that.   For now, you can check the demo that gives you about 50m in detection range  http://dev.ti.com/tirex/explore/node?node=AB8Rxv0tvZ0j0UT8TiJ8Fw__VLyFKFf__LATEST

    I am not family with zone occupancy detection demo, you will need to file a new e2e ticket regarding that. 

    Best,
