Hello,
1) In the OOB demo using the AWR1843 radar module, I would like to know how the signal-to-noise ratio (SNR) is calculated for each point. Specifically, I'm interested in understanding the detailed calculation process and at which stage, such as the Doppler FFT, the SNR calculation occurs.?
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;
2) According to this answer :
I discovered that the peakval is calculated in this way:
peakVal(dB) = DPIF_PointCloudSideInfo.snr/10 + DPIF_PointCloudSideInfo.noise/10
I would like to know what is the physical meaning of the peakval and why is it calculated in this way?
Best,
Ben Hassine
