IWR6843ISK: IWR6443 or IWR6843

Part Number: IWR6843ISK
Other Parts Discussed in Thread: IWR6443, IWR6843

Tool/software:

I am Pablo Crego from GMV, Aerospace and Defence. I am writing because we are interested in buying one radar from Texas Instruments. Specifically, we have chosen IWR6843 or IWR6443. We are not getting used to work with this kind of machines and I have several questions before using this radar for our project.

We are in a hurry because we need to complete the order this week but we need to clarify these questions:

  • We need to filter nearby obstacles built in aluminum alloys and to be able to detect far obstacles. Our intention is placed the radar in front of one big obstacle built in aluminum alloys. It is necessary to ignore the signal received from this surface and it should be possible to detect object behind that. We are reading the specifications of this radar, and we think that it is possible to do that with software or hardware filters. Is that correct?
  • We are really concerned with the SDKs and the rest of available data to help with the integration of this device. We were buying more electronics sensors with TI and we know that is you usually provide this kind of material. Precisely, we are going to connect that sensor to Jetson ZED Box Orin NX 16GB. Are there enough material to be able to do that?

I would like to detail that we are building a prototype now. But if this solution works properly, it will be built in large quantities in the future.

Thank you,

Pablo Crego

    Hello Pablo,

    So the intended use is to try and detect objects behind some sort of aluminum object? Is the intended to be INSIDE one of these aluminum objects, and then scan an area and ignore other similar aluminum objects? What are the intended to detect targets? What min and max ranges are of interest?

    Best Regards,

    Hello,

    We think that this radar, IWR6843 or IWR6443 is not enough for our intended use. However, I will be really grateful if I could know the answer to this question to be able to search for devices properly. Our main use is placed the radar in front of one big aluminum object. This sensor should detect obstacles behind that aluminum object, ignoring the big surface that covers this platform. It is not inside anything. It is free, but it has in front of its one big aluminum surface.Is it possible to do that with one radar? Otherwise, it is better to use one lidar? Could you propose some devices from TI that covers these specifications?

    Hello,

    Radar technology will not work. Radar waves physical characteristics make it bounce off of metal, not penetrate. It can penetrate thin fabrics, plastics, and simple surfaces, but not metal. You will need to look into sensors that are able to penetrate metal. LiDAR has even less penetrative capabilities as it is based on light.

    Best Regards,

    Pedrhom.
