N2 - Space-based Automatic Dependent Surveillance-Broadcast (ADS-B) technology has become a new research hotspot in the field of aviation surveillance due to its global coverage capability. While the space-based ADS-B system can solve the blind spots of the terrestrial ADS-B system, it also brings new problems such as weak ADS-B reception energy and increased signal conflicts. Aiming at the demodulation of weak signals for space-based ADS-B, this paper derived the signal-to-noise ratio (SNR) threshold for the demodulation of space-based ADS-B signal and analyzed the BER distribution as well as the relationship between SNR and correct decoding probability of the coherent demodulation method. Through simulation experiments and in-orbit data verification, the theoretical analysis of this paper met the actual situation, and the coherent demodulation method can meet the requirements of space-based ADS-B weak signal reception, which provides a direction for the improvement of the sensitivity of space-based ADS-B receivers.
