CCS/IWR6843: 3D People Counting Lab Q&A ( toolbox 4.2.1)

Toyota-1

Part Number: IWR6843

Tool/software: Code Composer Studio

Dear TI 

       . 

                  ISK cfg :     profileCfg 0 60.75 7 7 41.10 1184274 0 54.7125 1   96 2950.00 0 0 36

                 ODS cfg :    profileCfg 0 60.75 7 7 41.10 0 0 54.71 1 96 2950.00 0 0 24

                 Above the last parameter is RX gain , why ISK is 36 and ODS is 24 . Do you have unit for this parameters ,  db ?  and range ? 

                 ISK  1184274 , this is for what ?

    Hi Toyota,

    This is in dB. This will effect maximum range, but it will also effect noise floor. On the ODS, we have a much wider FOV, so there are more reflections off of floors and ceiling. This doesn't result in detections, but does increase the noise floor. Lowering the Rx Gain is a way to improve here and lower the noise floor. Since this is target shorter range applications, we don't need the higher Rx gain for long range detection.

    Regards,

    Justin

    Dear TI 

                  What is the suggestion value for below application?

                  0~10M , 0~20M and 0~100M

    Hi Toyota,

    This will depend on Tx Backoff as well as the environment. In General

    0-20 meters: 24 - 36 dB Rx Gain.

    For 100 meters, you will definitely need 48 dB Rx gain to detect a human.
