Summary In this paper, a transmit‐sense‐receive mode–based simultaneous transmit‐and‐receive cognitive antijamming (SCAJ) strategy is proposed to enhance spectrally efficient of airborne networks in congested electromagnetic spectrum environment. We explore the performance of spectrum sensing based on energy detection in SCAJ system. The tight close form expressions of jamming detection and false‐alarm probability are derived under different channels, the throughput of individual SCAJ system is analyzed, and SCAJ transceiver‐based airborne ad hoc network capacity is presented for air platform equipping with digital beamforming antennas. Simulation results show that proposed SCAJ technology can improve the antijamming capability and airborne ad hoc network capacity compared to the half‐duplex cognitive antijamming scheme. It is an effective approach to solve the problem of designing airborne networks arise from the limited availability of spectrum and the desire to provide much higher data rates.
