    Hello,
    

    I hope you're doing well.
    

    I recently watched the Drone Tracking Radar: Part 7 – Longer Range and MTI Processing video and get the same radar used in the demonstration. I attempted to replicate the experiment using the Range_Doppler_Plot.py script from GitHub, but the output appears much noisier compared to the results shown in the video. The difference is significant.
    

    We have tested the setup in multiple environments with minimal interference, yet the noise persists. We suspect the issue might be related to calibration files, but we are unsure. Have others encountered similar issues? Could the problem be linked to calibration?
    

    We would greatly appreciate any guidance, as we are currently stuck at this stage.

        Dear Kiloa,
        

         
        

        Did you try to implement the MTI 2-Pulse or 3-Pulse Canceler in Range_Doppler_Processing.py to reduce clutter?  This option is also contained in the Range_Doppler_Plot.py code.  This MTI option is contained in the Python code, and it will work when turned on.
        

        You can also add CFAR to the Range_Doppler_Processing.py and Range_Doppler_Plot.py programs to further reduce clutter.
        

        You will need to use your Phaser in an open area, such as a field, to minimize reflections from nearby objects, such as buildings or trees.  Are you able to do this?
        

        Finally, you can verify that the Phaser board hardware is operating correctly by running the phaser_prod_tst.py.  The code will tell you if there are any problems with the hardware.
        

        Respectfully,
        

        Scott

        You may also need to adjust the min/max intensity levels (min_scale and max_scale).
