Hello,
I would like to measure the distance between two USRP devices by transmitting a signal from one USRP and using the other as a transponder. The second USRP should receive the signal and immediately retransmit it. By measuring the round-trip time delay, I aim to estimate the range between the devices. I plan to implement this using the B200 Mini and am flexible regarding whether transmission and reception occur on the same channel or separate channels.
I have a few questions regarding implementation:
- Can the USRP accurately measure the delay, and is it possible to calibrate the internal delay introduced during transponding?
- Is it possible to configure the USRP to perform this function without an external host computer? If so, how?
- What range accuracy can be achieved for distances between 200m and 3km?
- Is FPGA programming required for this application, or can it be implemented using a host computer via the USB interface?
Thank you for your time and insights.
David
