Original question:

CCS/IWR1642: IWR1642 SRR

Tool/software: Code Composer Studio

I found a similar problem when using SRR,I put the radar on the side rear of the car as a Blind spot  detection System.
When I drive at a speed of less than 30km / h along the guardrail of the road, it seems that everything is OK,When the driving speed is more than 30 km / h, multiple closing targets will appear stably.These close targets are original target points, not tracked targets,I want to know how these close targets come about?

    HI,

    Please let us know which configuration is being used.

    Can you please provide a short video of the point cloud?

    the configuration is same with the SRR demo.

    we use our own GUI.

    Hi,

    As mentioned in the other thread, we would need to be able to collect the raw data to understand what is happening.

    Without the raw data it is very difficult to debug

    thank you

    Closing this thread since there is no additional support possible without raw data collection.

    Thank you

    Hi,

    I find a similar issue, working with SRR. I have one radar in front and at the back of the vehicle.

    When the vehicle self velocity is high enough, among the correct points there are some opposite - going (wrong Doppler) detected points.

    Looks like the velocity disAmbiguateVel function is making some wrong calculations.
