IWR1443BOOST: Measure surface velocity of water using IWR1443

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1443, IWR6843, , IWR1642

Hello,

I want to measure the surface velocity of water using IWR1443. Shortly, I am going to conduct experiments using the out of box demo. Could you please point out me resources which would help me in this? Any particular labs, algorithms, configs, etc which would help me to get this done or increase the accuracy of the measurement. Thank You.

    Hi Rohan,

    I'd recommend purchasing an EVM and trying the labs on the TI Resource Explorer.

    One such lab is the Zone Occupancy demo which may help to provide a clearer visualization of your scene.

    Is there a reason you have selected IWR1443? Outside of low-power requirements, the IWR6843 is recommended for most Industrial Applications.

    Zone Occupancy is the demo for IWR1443 but the Area Scanner is the recommended lab for IWR6843.

    Let me know if you have more questions!

    Cheers,

    Akash

    Thanks, Akash for your reply. Actually, I was previously working on a project on water level measurements and for it, I used IWR1443Boost EVM with high accuracy lab and obtained very good results. I am hoping to measure surface velocity with the same EVM. I will try with Zone Occupancy and will let you know the results.

    Regards,

    Rohan.

    Hello Akash,

    I got IWR1642 also a few days back. Recently, I conducted experiments to measure the surface velocity of water in an open-channel flume (with flow speeds ~0.2 m/s) with both IWR1443 and IWR1642. The results I got are very promising. IWR1642 performed much better than IWR1443. I used the out of box demo and observed the doppler vs range plot of demo visualizer during the experiments.

               I want to reduce the scattering of data points and make my data points more concentrated and steady. On the hardware side, we are considering to use Horn Antenna or dielectric lens for the antenna to possible make our beam more focused and limit the fluctuations.

            I want to hear from you what can I possibly do on the software side, are there any algorithms or labs in your knowledge which could help me to get better results? Or any alterations that I can make in the existing Out of Box code? Any suggestions are welcome.

    Regards,

    Rohan Saxena.

    Hi Rohan,

    I do not have many recommendations on the software side, your suggestions on the physical hardware side are definitely spot on. I'd also recommend using just 1 Tx and 1 Rx.
