We only need labview to control the USRP, so that we can tell the USRP to record samples from its input RF port, store these samples into an IQ file, and then tell the USRP to read this IQ file or another IQ file that we may have (e.g. generated using our Skydel simulator) so that the samples inside of this file are converted into an RF signal that is output by the output RF port of the USRP. We want to generate a spoofer to detect spoofing and after detecting we have to mitigate.
