IWR6843: IWR6843 threshold of detect setting,and the parameter of human detecting

Part Number: IWR6843

I have four question of IWR6843 detect performance.

1.In addition to CFAR，is there other threshold parameter to adjust for detecting more things？

2.If we want to enhance the ability to detect far，can we use two sets parameters for near and far？How to do.

3.Does IWR6843 test detecting performance,can you afford test result like document SWRA593.

4.Please provide the parameters set of detecting people using IWR6843.

Thanks

Hi,

Please use sensing estimator to play around with various parameters:

1.The attachment is our parameter,moving human can be detected only 10m. I cannot find the problem.

We have tested antenna performance,same as TI demo board.

2.Estimator save format is .json,how to import into visualizer?

Thanks.

Hi,

What the max range that you are looking for human to be detected.

Thanks

Human 20m should be detected.

Car 50m, and car max speed is 50KM/h.

Thanks.
