MMWAVEICBOOST: IWR6843ISK: Relation between SNR and Noise fields received from device

Shraddha

Part Number: MMWAVEICBOOST

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 learn the exact relation between SNR and Noise fields received from the device.

Could you please help regarding this ?

Thanks

Hi,

Please refer to file @C:\ti\mmwave_sdk_03_04_00_03\packages\ti\datapath\dpif\dpif_pointcloud.h

typedef struct DPIF_PointCloudSideInfo_t

{
/*! @brief snr - CFAR cell to side noise ratio in dB expressed in 0.1 steps of dB */
int16_t snr;

/*! @brief y - CFAR noise level of the side of the detected cell in dB expressed in 0.1 steps of dB */
int16_t noise;
}DPIF_PointCloudSideInfo;

Thanks

Hi Yogesh,

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?

Thanks
