AWR1642: board choosing of automotive radar application

Part Number: AWR1642
Other Parts Discussed in Thread: , TIDEP-0092

Hello there,

i am a researcher who work on pedestrain /cycler detection and recognition algorithm developing , and I want to find an appropriate board for me to do some experiments.  I have seen the automotive radar sensors in TI products, the AWR1642BOOST can be used as a SRR to do this, but its range resolution is not good enough. Is there any product of AWR1642  or other radar sensors to achieve higher range resolution? I don't have much hardware knowledge, only basic level.  I have also seen a video from youtube(the name of the video is: Short range radar demonstration using TI’s mmWave sensors) , it can achieve 4cm range resolution, it's super, but I cann't find any details of it. Would you please give me any help? Thank you in advance!

Best Wishes,

Kathy

    Kathy,

    What kind of range resolution are you trying to achieve? It is true that the AWR1642 is capable of achieving a theoretical range resolution up to 4 cm based on a 4 GHz chirp.

    I would suggest reviewing this white paper to better understand the relationship between the different chirp parameters and the corresponding radar capabilities.

    Hello Kyle,

    thank you for your reply. I know AWR1642 can achieve 4cm range resolution which is quite suitable for me. I want to buy a board which can reach 4cm range resolution . Can AWR1642BOOST reach 4cm range resolution? And could you please tell me what's the difference between TIDEP-0092 and AWR1642BOOST? Are AWR1642BOOST and AWR1642 EVM the same thing? Thanks a lot.

    Best regards,

    Kangle

    Kathy,

    There is no difference between TIDEP-0092 and AWR1642BOOST. TIDEP-0092 is a reference designed that utilizes AWR1642BOOST.

    Additionally, AWR1642 is just the device. AWR1642BOOST is the EVM that uses AWR1642 in addition to the antenna pattern and other connections. If you are looking to evaluate our device, I would strongly recommend obtaining an AWR1642BOOST.

    And yes, with the AWR1642BOOST and a 4 GHz bandwidth chirp, there is the possibility of resolving a range resolution of 4 cm.

    Regards,
    Kyle

    Thank you very much! I have booked AWR1642BOOST from TI. Thanks again.
