Tool/software:

HI,

I am interested to know about the IWR6843AOP EVM board. When I looked into the User guide, there (section 7) I saw IWR6843AOPEVM (Deprecated), is this not in production? Do you have more details about this? 

Regards,

Aswini

  • Hi Aswini,

    IWR6843AOP EVM (or any TI EVMs) are only for development purpose and are not in production.

    You can get details on IWR6843AOPEVM in the below page:

  • Hi Swarnendu,

    Thank you for your reply,

    Is the IWR6843AOP IC in production? What is the mechanism used to sense the data in this IC ?

    Regards,

    Aswini

  • Hi Aswini,

    Yes, the IWR6843AOP device is in production. You can find all details in the product page: 

    IWR6843AOP data sheet, product information and support | TI.com (link)

    IWR6843AOP is a 60GHz millimeter wave radar sensor with Integrated 4 receivers and 3 transmitters Antennas-On-Package.

    It uses frequency modulated continuous wave (FMCW). Radar systems transmit electromagnetic wave signals that objects in their path then reflect. By capturing the reflected signal, a radar system can determine the range, velocity and angle of the objects. The transmit (TX) signal is a single tone with its frequency changing linearly with time. This sweep in frequency is commonly referred to as a “chirp”. A set of these chirps form a “Frame” and this can be used as the observation window for the radar processing. For more about FMCW operation please refer to the below application note:

    IWR6843AOP supports a complex baseband architecture, which uses quadrature mixer and dual IF and ADC chains to provide complex I and Q outputs for each receiver channel. It has a 200MHz Cortex R4F user programmable processor. It also has a 600MHz C674x DSP engine. 

    Please find the device datasheet in the product web page. Below is the direct link to the device data sheet:

  • Hi Swarnendu,

    Thank you for your reply,

    1. What type of antenna is used in IWR6843AOP ? Is any specific reason for placement of the TX and RX antenna in the device

    2. Is any assistant devices used to detect the movements of the object

    3. what type of algorithm is used to detect the movements

    4. How they scan the area is any pattern used for this? How do we ensure that the reflected wave is from the particular object?

    5. Is it sends the wave continuously, Could you please explain the working principle? 

    Regards,
