CCS/IWR1642: question about SRR demo

Part Number: IWR1642
Other Parts Discussed in Thread: DCA1000EVM

Tool/software: Code Composer Studio

Hello, I found the following problems when testing SRR demo

1.When the vehicle speed installed with radar is greater than 70km/h, it is found from matlab GUI that there are multiple approaching targets, but there is no target on the road.

2.Is the maximum speed you tested 90km/h or 172km/h?Because using the velocity expansion theory, the maximum value is 3 times the velocity value.

    Hi,

    We have to check with the team who validated this algorithm and will get back to you early next week

    thank you

    hi,How is it going?I would like to add to this question: when the vehicle speed is relatively high (>90km/h,, radar is installed in the rear of the vehicle), an approaching target will appear after passing the green belt, the target velocity is about -8m/s, of course, this is only one of the values.The road is actually not any near the target.

    Hi Tecman, 

    Could you share a movie of your observations/ 

    Regards

    Hi Tecman, 

    Thank you for the video. It looks strange, and I agree that no target should have been detected. Is it possible for you to collect ADC data of such a situation? I am wondering if it is the road clutter that is confusing the Kalman filter. 

    Regards

    I did not collect ADC data.Because when I use DCA1000EVM, I'm not sure when this is going to happen, can't see the target in real time.

    Hi Tecman, 

    It is difficult to imagine what is happening there without ADC data. Could you try and analyze some ADC data of this particular scenario? 

    Regards
