**Part Number:**MMWAVE-STUDIO

**Other Parts Discussed in Thread:**AWR1843, AWR2243

**Tool/software:**

I am using DCA1000 to get the data from AWR1843. I used postProc button in mmWave studio to see the plots corresponding the obtained raw data.

But I am trying to develop the script to generate the plots like rangeDoppler plot, rangeDoppler plot and pointCloud plot.

From tidueo9.pdf, I figured out that the processing of the raw data requires steps like

1) Range-FFT,

2) Dopple-FFT,

3) CFAR deptection,

4) Angle estimation,

5) Clustering.

From section 2.1 of tidueo9.pdf, I am able to perform the Range-FFT and Doppler-FFT and get the rangeDoppler plot.

But I am unable to apply CFAR. In tidueo9.pdf it is told that the **CASO-CFAR detection in applied in range domain, CA-CFAR detection is applied in Doppler domain **on rangeDoppler data.

Generally, CFAR is performed by comparing the cell under test (CUT) with a threshold. This threshold value varies depending on the CUT, The threshold for each CUT is obtained by multiplying the noise estimate calculated from the neighborhood of CUT with a scaling factor.

But in the **miscellaneous options window** of postProc in mmWave studio**,** it is mentioned that for CA-CFAR threshold is 18dB. But in CFAR the threshold is not constant.

So I am not able to get how the CFAR is appled by postProc of mmWave studio.

Also, in tidueo9.pdf it is told that the **CASO-CFAR detection in applied in range domain, CA-CFAR detection is applied in Doppler domain.** But **miscellaneous options window** selected CA-CFAR method only. So I am confused.

Please tell how CFAR is applied on RangeDoppler data for obtaining the point clouds for AWR1843
