Part Number: IWR6843

Which mmWave product is appropriate to Near range use (0.5~1m)?

What kind of factor do I have to consider to realize the Near range feature?

How are the minimum range and the minimum resolution defined?

Thanks and Best regards,

Tsurumoto.

Hello,

TI mmWave sensors will be able to detect to objects in the near range. Our product line up differs in number of transmitters and internal processing capabilities such as more memory or the addition of a DSP. For more information about our line up, please see this product page: https://www.ti.com/sensors/mmwave-radar/industrial/overview.html

Minimum range resolution is defined by the chirp bandwidth. For a 4GHz chirp, the range resolution is about 4cm. Minimum range is defined by the sample frequency and slope of the chirp ramp. For more information on how our radars work, please see this mmWave training: https://training.ti.com/intro-mmwave-sensing-fmcw-radars-module-1-range-estimation?context=1128486-1139153-1128542

I would highly recommend that the customer purchase an IWR6843ISK Evaluation Module: https://www.ti.com/tool/IWR6843ISK

After purchasing, please experiment and test with the Out of Box Demo: https://dev.ti.com/tirex/explore/node?node=AM1kRI3l5vvDUDVn-RHrxQ__VLyFKFf__LATEST
