Please see comments below. AD9361 datasheet contains performance metrics for your requirements either directly or indirectly via calculation:

dynamic range: >100dB
- do you mean linear dynamic range or spurious. If it is spurious than no.
Resolution: <5cm
- I think that this is a function of max frequency, i.e. 5GHz in your case.
Range: <3m
- I think that this should be fine.
noise floor: <-150dBm/Hz
- also fine I think since Tx noise floor is -157dBm/Hz
high receiver sensitivity
low receiver noise figure: <3dB
- noise figure may need to have to be improved with an external LNA at higher frequencies (it ranges from 2dB up to 4dB over 70MHz to 6GHz range).
low IF bandwidth
- 50kHz can be supported
freq range: 1GHz to 5GHz
- not a problem since frequency range of the part is 70MHz - 6GHz
