IWR6843: Range resolution of this device?

Please review range resolution section of linked document

Thanks for response. I already read that document. That document is for the case that all 4GHz is available for base band which is not the case for this chip. In the manual, it mentions the IF bandwidth frequency is 15MHz. I have attached an image of the receiver from the manual. In receiver after mixing with the chirp, the BW is 4GHz, but manual says it is 15MHz. What happens in the middle? For range resolution, I should use 15MHz or 4GHz as bandwidth?

Hi,

All 4Ghz is available for all the Radar devices. The IF bandwidth is not the same as the TX signal bandwidth.
The 15MHz limits the maximum range that can be sensed but this can be improved by decreasing the slope of the TX signal. IF bandwidth depends on the time delay with is a function of distance.

I understand this. My question here is not range ambiguity. Its RESOLUTION. For resolution, the available bandwidth is 15MHz according to your explanation which means 10 meter resolution, am I correct?
