IWR1642: OOB demo distance X, Y question

Hi,

I use OOB demo v2.1.

Check point-2, axis are x = 0.879, y = 0.225, form range profile plot to see, why point-2 range (meter) is 0.88 m?

e.g. point-3, axis are x = -0.20, y = 2.07, so range (meter) is close to 2.07 m

Thanks.

Hi User,

So the x, y, z components are resolved from the range itself through the angular information that is obtained as well. Essentially range is the magnitude of each of the components.

You'll notice that point 3 is dominated by its y-component while point 2 is more dominant on the x-component (range appears to be more than .9).

Let me know if you have more questions.

Cheers,
Akash

Hi,

I checked OOB v3.0 and v3.1 are same problem.

Distance 0m ~ 1m, is different Y axis, but over 1m, the distance is same Y axis.

Why?

As I stated before, the distance labeled 'range' will be the magnitude of the x, y, and z components.

Hi,

I'm still confused...

By the way, we check point-2 again, I use corner reflector, the real distance is 22 cm, but form range(meters) plot to check is 0.8 m (80 cm)

So, the distance is not true, can you double check this?

My chirp setting as attachment, thank you.

Hi Tim,

Are you still seeing this issue?

The chirp configuration looks good but I can't provide much without seeing your plot and range profile. My guess is that you are looking at two different detected objects in your scene.

Would you be able to post a screenshot?

Cheers,
Akash

Hi Tim,

Since we haven't heard from you I hope you were able to resolve your issue. If you still have more questions feel free to open up a new thread!
