IWR6843ISK: Lens recommendation for high accuracy lab

Part Number: IWR6843ISK
Other Parts Discussed in Thread: IWR6843, IWR1443

Hi,

I'm trying to test a high accuracy lab with IWR6843ISK I have. The guide document states that a lens may be required to achieve millimeter level accuracy.
Do you have lens recommendations for IWR6843ISK?

And, should I consider other radar to reach higher range resolution and maximum range?

Thanks.

  • Hi Jinhyeong, 

    We have a few vendors we recommend for lenses:

    IWR6843 is recommended for your use case.

  • Thank you for reply,

    Are there any caveats to using radar with lenses?

    (ex. For Radome, the distance from the antenna must be n/2 multiples of the wavelength)

     

    And, for the lens from THORLABS(LAT151), it is stated that the design frequency is 500 GHz. The frequency of IWR6843 is 60-64 GHz, can I use it?

    This summer alone, we saw the release of 'The Green Lantern,' 'Thor,' 'Captain America' and 'X-Men: First Class.'
    올해 여름에만 '그린 랜턴', '토르', '캡틴 아메리카', '액스맨: 퍼스트 클라스' 등이 개봉되었다.

    In addition to these films, Portman has several movies coming out in 2011, including the super hero film 'Thor'.
    이 영화들 외에도, 2011년에 개봉될 수퍼히어로 영화 '토르'를 포함해 여러 편의 영화에 출연할 것이다.

    The film will be rewritten by Mark Protosevich, who also wrote 'Thor' and 'I Am Legend.' The lead actor for the film has not been decided yet.
    이 영화는 마크 프로토세비치에 의해 다시 쓰여질 것인데 그는 '토르'와 '나는 전설이다'를 썼다. 이 영화의 주인공은 아직 결정되지 않았다.

  • Jinhyeong,

    A lens will allow you to focus the beam and increase your maximum distance.  There are numerous resources and papers online that explain advantages/disadvantages of using a lens, and the implementation of a lens in a radar system.  From TI, we have the following mmWave Radar Radome Design Guide.

    In regards to the THORLABS lens, we have done testing and experiments with the lens at the link I sent on the IWR1443 device.  The performance was very good for the 4 inch and 3 inch lenses, while performance was poor for the 2 inch lens.  For example, the gain for the 4 inch lens resulted in a maximum distance of 225m.  You can find the different lens sizes here: thorlabs.com/newgrouppage9.cfm?objectgroup_id=1627&pn=LAT151
