have you read what you linked? there are no reflections here, this is not SDR, just reading RSSI.

Yes. :)

Would you like to offer up another term for something that performs ranging with radio?

And how does this exclude it from being called radar?

radar is based primarily on time delays, secondarily on doppler shift, the signal intensity is not such a major factor since it varies a lot depending on the incidence angle of the target.
