    I looking to to use the recieved signal data, so I can write my own equation to decided what is considered movement and what is not ( I want to do my own processing)? what is the best way to extreact RS data?
    (The RAW data used to determine the movement)
    Thanks.

    Hi Anwar,
    I reckon that you need raw data from radar. XeThru sensor support RF data and Baseband data output.
    In Module Connector, there is one example named XEP_X4M200_X4M300_plot_record_playback_radar_raw_data.py which can be used for radar raw data extract, you can also record these data on specific format.

    Hi Anwar,
    Please, the example python code "XEP_X4M200_X4M300_plot_record_playback_radar_raw_data.py " can be found in "pymoduleconnector\examples" folders in the latest Module Connector for windows (ModuleConnector-win32_win64-1.5.3).

    I was wondering what the X & Y represent? is it amplitude in V and time in ms

    It is amplitude in y-axis and Range bin in x-axis. Range bin is related to distance. The distance between two range bins is 0.64cm for RF data; It is 5.14cm for baseband data.

    since I am using "XEP_X4M200_X4M300_plot_record_playback_radar_raw_data.py" I was wondering if I can access the variables for distance, time and do my own processing. I could not identify the variables, if you can point them to me that would be great!,
