IWR6843ISK: Relation between SNR and Noise fields received from device

Shraddha Swami
Intellectual 370 points
Part Number: IWR6843ISK
Other Parts Discussed in Thread: MMWAVE-SDK

Hi TI Team, 

We are working on Area Scanner Zone Demo application from TI Industrial toolbox. We are able to parse the different TLV's data received from device. In one TLV , we are receiving SNR and Noise data. We would like to understand the relation between the SNR and Noise in object detection. Can we get some document related to SNR and Noise calculation algorithms? How SNR and Noise is getting affected when object is passed in front of the RADAR? 

Could you please help regarding this ?

Thanks

    Hi Shraddha,

    Please look at the following resources:

    1. MMWAVE-SDK doxygen documentationat C:\ti\mmwave_sdk_03_04_00_03\docs\mmwave_sdk_module_documentation.html.
      • Specifically, go through the CFAR DPU documentation. I have also copied the direct link here:  file:///C:/ti/mmwave_sdk_03_04_00_03/packages/ti/datapath/dpc/dpu/cfarcaproc/docs/doxygen/html/index.html
    2. CFAR DPU source code:
      • C:\ti\mmwave_sdk_03_04_00_03\packages\ti\datapath\dpc\dpu\cfarcaproc\src\cfarcaprocdsp.c. Look at the following function and the comments above it to get an idea of the algorithm and calculation : CFARCADSP_cfarCadB_SOGO()
