IWR6843ISK: What are the steps to generate a radar data cube from raw data captured via LVDS in an OOB (out-of-box) demo with BPM

Other Parts Discussed in Thread: DCA1000EVM

How can I generate a radar data cube from raw data captured via LVDS in an OOB (out-of-box) demo with BPM (Binary Phase Modulation)? I've attempted to use the `rawDataReader.m` MATLAB example provided in the mmWave SDK, but it seems to work only for 1 TX and 4 RX settings.

I'm seeking guidance on generating a radar data cube using raw data captured with DCA1000evm in the OOB demo with a multiple-antenna setup. Additionally, I'm interested in learning how to generate point cloud data from the raw data file. Your insights would be greatly appreciated.

    Hi,

    I would recommend modifying the existing script to support multiple antennas. You'll want to do the BPM demodulation (compute (TX1+TX2)/2 and (TX1-TX2)/2), and potentially do your own elevation FFT as well, or coherently combining the results from multiple azimuth measurements if you have more than 4 azimuth antennas.

    Best,

    Nate
