RF Convergence with GNURadio
summary
A GNURadio implementation demonstrates joint radar–communications by running a temporal mitigation block on over‑the‑air signals captured with GNU Radio and Ettus USRPs. Setup uses one transmit antenna and a four‑channel receiver, an LFM radar (time‑bandwidth 100) at −10 dB and a BPSK communication signal at +10 dB overlapping in spectrum. The system decodes and cancels the stronger comm waveform iteratively, after which radar range‑Doppler peaks that were buried by interference become clearly visible, validating the algorithm on hardware.
