IWR1443BOOST: Horn lens info. for Fluid-level sensing demonstration using TI mmWave sensors

Hitoshi Sugawara

Part Number: IWR1443BOOST

Hi Experts,

 

Fluid-level sensing demonstration using TI mmWave sensors:

https://www.youtube.com/watch?v=aI1DNkGDb0g

There seems a white horn lens on the IWR1443BOOST utilized for this demo.

( It can be seen at 0:17 in the video. )

 

Could you please let us know how the horn lens is mounted onto the IWR1443BOOST.

Does it contact directly on the pattern antenna?

Does it work if the horn lens is attached to an enclosure which IWR1443BOOST is installed inside?

 

We would like to know its size too.

Form the accuracy measurement point of view, is it better to utilize TX x1 with Rx x4?

 

Hope if it would be available to purchase in the market.

 

Thank you for your kind reply.

Best regards,

Hitoshi

    Hello Hitoshi,

    We don't have those specific details available and we are not even in possession of the lens anymore but I will talk with our antenna expert to get you more information.

    Cheers,

    Hi Hitoshi,


    Does it contact directly on the pattern antenna?

    The lens has to be placed a certain distance (equivalent to the focal length of the lens) away from the antenna.



    From the accuracy measurement point of view, is it better to utilize TX x1 with Rx x4?

    By Tx x 1 and Rx x4 do you mean using one Transmitter and Four receive channels or do you mean using transmitter number 1 and Receiver number 4. With the lens we preferred this (i.e. transmitter number 1 and Receiver number 4 )as the opening of the lens was not wide enough to cover the other TX or RX recievers



    Lastly, do you know where more are available for purchase?

    As far as I know they are not available for purchase.


    Cheers,
    Akash

    Hi Akash,

    Thank you for your reply.
    Regarding the placement of the lens, we will work with local manufacture to get more information.

    For the second question, we believe that MIMO ( with 4 RX antennas ) would be better solution from the accuracy range measurement point of view.

    Thank you again.
    Best regards,

    Hello,

    I am also interested to know where to buy, or possibly how to design such a lens.

    Thanks, Tom
