AWR2944: streaming of data over ethernet, preferably radar cube data

Gunter Schmer

Part Number: AWR2944
Other Parts Discussed in Thread: AWR2544

Tool/software:

Hi,

one of our customers needs to use an ethernet based setup such as the AWR2944 to stream radar cube data over ethernet with timestamping.

Is there a reference project that can be used as a starting point to enable this?

Alternatively we have also thought about the AWR2544, and the same question applies there as well, if such an example exists.

Thanks!

    Hi,

    I am looking at the following for AWR2544

    Millimeter Wave (mmw) Demo for AWR2544

    It seems this example in fact streams out the data cube over ethernet. Please confirm.

    Another question is: Is there a PC side application that can receive the ethernet packets and operate on them, e.g. store them into files, or even let a python script do further processing and visualize heatmaps. 

    Thanks!

    Hi Gunter,

    AWR2544 demo use case is to stream out compressed 1D FFT output data over ethernet.

    We also have the python-based scripts to store these outputs on PC. You can then use our matlab scripts to decompress, do further processing and view the data.

    Hi Ajay,

    that sounds promising, and if I understand correctly, the 1DFFT output is then actually the whole radar cube data. Please correct me if I am wrong.

    What limitations do we see on workable chirp configurations, framerate, CPU loading etc to have enough bandwidth to stream radar cube data out over ethernet?

    Thanks!

    Hi Gunter,

    In AWR2544, Raw ADC data is generated by the front end, This Raw ADC data is then sent for 1D FFT (Range FFT) and this 1D FFT is then compressed using a compression algo. This compressed data is what is transmitted over ethernet.

    At receiver end, the central processor has to decompress the data and do further processing like Doppler FFT, AoA etc to get the final point cloud.

    AWR2544 has 1Gbps ethernet speed, so with compression you should be able to stream out data quite comfortably with enough bandwidth.
