IWR6843ISK:Increasing the range of the IWR6843ISK

IWR6843ISK: longrange people detection config parameter Tuning

Part Number: IWR6843ISK

Hello,

I have a question

long range people tracking

(6843_100m_2D_advanced.cfg)

We need to visualize it quickly to speed things up.


* Change and adjust frame scan from 400ms to 100ms
* Change and adjust human detection distance from 100m to 30m

Which parameters in config should I change?

You will need that document.

Best,

    Hi,

    You can find these arguments documented in the MMWAVE SDK docs/ folder. It looks like the final argument of subFrameCfg sets this value, but you may need to make more drastic modifications to the chirping configuration to achieve this, as you may not have enough time to do all the chirps and processing in 100 msec. 

    Have you considered using the 50 meter configs instead? They have a reduced detection range and a faster frame time.

    Best,

    Hi,

    I want to use it as

    distance: 30m
    frame time: 100ms

    The figure above shows the comparison before and after configuration modification. However, there has been no change in frame time after running the modified configuration. What other parameters need to be changed? Thank you for providing parameter values. Please provide parameter values.

    Hi,

    As I asked above, have you considered using the 6843_50m_2D.cfg instead? It has a 100 msec frame time and reduced range.

    Hi,

    I'm trying to use the 6843_50m_2D.cfg file as you suggested. There's a condition I want to modify when using this config.

    I want to change the FOV to -/+ 40 degrees.

    So, I've modified the cfarFovCfg parameter. Is changing this parameter correct? And if so, will changing only this parameter adjust the FOV?

    Best,

    Hi,

    Please see the MMWAVE SDK Users guide found at C:\ti\mmwave_sdk_03_06_00_00-LTS\docs. There you will see that the cfarFovCfg is used for filtering in the range and doppler dimensions. Use the AoAFoVCfg to filter in the angle dimension.
