TDA3XEVM: How RDM is generated and the energy is calculated by CFAR for CUT

Yao Yu

Part Number: TDA3XEVM

1. We compared the RDM directly output from TI board and the RDM generated by applying 2D-FFT to raw ADC data divided by 16, and found that the elements of the former is much less than the latter. Could you elaborate on how RDM is generated by TI? Is the value of RDM elements in log2 domain?

2. In the CFAR detection list ouptut from TI board, there are indices of Doppler and range bins and the associated energy (see attachment). I used the indices of the detected bins and found that the energy is quite different from that shown in detection list. How is the energy of the detection list calculated ?

3. How are the multiple channels combined to do CFAR? Noncoherently combining, i.e., log2(abs(rdm_0).^2+...+abs(rdm_N).^2)?

Hi Yao,

Please find my answers inlined :

>>> The output of 2D FFT is not in log domain. What is the FFT dimension for range and doppler which you are using. Also what is the input data range?

>>> Output energy of the peak detection applet is stored in binary log format thats why it could be very different from actual energy.

3. How are the multiple channels combined to do CFAR? Noncoherently combining, i.e., log2(abs(rdm_0).^2+...+abs(rdm_N).^2)?

>>> First we calculate the sum of energy across multiple channels ( not in log domain), this energy sum is in 32 bit. This is then coverted to 16 bit energy by using binary log.

Regards,

Anshu

Hi Anshu,

The attached file target12.txt is detection list of CFAR. You can see the energy output is more than 2000. It looks like not log2 value.

Frame 12: VelIdx: 0, Velocity - 0.00 m/s, RangeIdx: 35, Range - 45.15 m, Energy - 4827

...

The attached file RDM12_Rx0.txt is 2D FFT output. The rangeXDoppler dimension is 256X128. The amplitude of RDM varies from 0 to 384.9480.

Thanks

Hi,

Can you refer peak_detection_cn function to see the processing which is happening for peak detection. You can find this function in peak_detection_tb.c file which is located at apps\peak_detection\test\src. Following is the function which is converting 32 bit energies to 16 bit energy :vcop_peak_detection_binlog_energy_scaling_cn

Regards,

Anshu

Hi,

Another point which I forgot to add is that as EVE is a fixed point processor the energy is stored in a Q format, that is why it could be large. You can refer PEAK_DETECTION_TB_LUT_Q_FORMAT ( 8) to see the Q format used for the energy

Regards,

Anshu
