The prospects of the inband full-duplex (IBFD) technology are praised in non-military communications as it allows each radio to simultaneously transmit and receive (STAR) on the same frequencies enabling, e.g., enhanced spectral efficiency. Likewise, future defense forces may significantly benefit from the concept, because a military full-duplex radio (MFDR) would be capable of simultaneous integrated tactical communication and electronic warfare operations as opposed to the ordinary time- or frequency-division half-duplex radios currently used in all military applications. This study considers one particular application, where the MFDR performs jamming against an opponent's radio control (RC) system while simultaneously monitoring RC transmissions and/or receiving data over the air from an allied communication transmitter. The generic RC system can represent particularly, e.g., one pertaining to multicopter drones or roadside bombs. Specifically, this paper presents outcomes from recent experiments that are carried out outdoors while earlier indoor results are also revisited for reference. In conclusion, the results demonstrate that MFDRs can be viably utilized for RC signal detection purposes despite the residual self-interference due to jamming and imperfect cancellation.
