sample rate.
1- I have a same radar application and I implemented the TX/RX code with two
methods in GNU Radio: with RFNoC_Replay and also with simple USRP sink/source
blocks.

Hi Shane,
I've had success using DPDK with ~200Msps rates over a QSFP+ link to a USRP
N320. I still have the uhd.conf file from that project but do not have the
hardware on hand to try anything.
