In this letter, the effect of hardware impairments on two-way satellite-terrestrial hybrid relay networks is analyzed. The terrestrial relay is considered as a two-way relay, which can transmit signals to both the satellite source and the mobile source simultaneously. Specifically, the closed-form expression, the asymptotic expression at high signal-to-noise rates and the throughput for the considered system are derived. The expressions show that the impairments greatly affect the system performance and system performance will be worse when the impairment level is larger. In addition, numerical results are provided to show the correctness of the analytical results.
