Part Number: TSW1400EVM Hi, I am a student using the TSW1400EVM to extract original data from IWR1443 radar, in order to apply further signal processing. And there are some troubles. Firstly, I have applied the code from Section 9.1, Page 15 in this doc: Mmwave Radar Device ADC Raw Data Capture (Rev. B) and got a matrix with 4 rows. I can totally use FFT method to handle one-row matrix and draw the range bins, but I do not know how to deal with this 4-row matrix. In other words, I am wondering why it uses 2 Tx and 4 Rx antennas to transmit the signal rather than single TX-RX antenna pair. I don't know the physical meaning of doing so. Could you please provide any relevant experience or suggestion? Thanks!
