Other Parts Discussed in Thread: AWR1642
Hi,
I had got the TLV binary data from UART data port and parse them based on SDK 3.2.0.4.
I had studied the "Output Information Sent to UART" section rom index.html document , but still have some questions as follows.
1. About the "range profile" (tag=2), the doc shows "The points represent the sum of log2 magnitudes of received antennas expressed in Q9 format." .
Question-1 : Do we need to divide all values, (Range FFT size) x (size of uint16_t), with 2^9 (Q9 format) to get the power(dB) value when plotting the range spectrum ?
Question-2: Are the above values are the relative power(dB) like as the ones of "the Range profile for zero Doppler" on TI demo visualizer?
2. About the "Side Information of detected objects" (tag=7), the doc show " snr - CFAR cell to side noise ratio in dB expressed in 0.1 steps of dB and noise - CFAR noise level of the side of the detected cell in dB expressed in 0.1 steps of dB. "
Question-3 : How to calculate the intensity (log) based on the int16_snr and int16 _noise data ?
Thanks for your help.
Best Regards,
A-Kai
