In order to solve the problem of incorrectly decode the ADS-B signal and the missing aircraft information caused by overlap and interference, in the information transmission process of 1090ES ADS-B signal, a multi overlapping 1090ES ADS-B signal separation algorithm based on RLS algorithm is proposed. After a comprehensive analysis of the ADS-B signal to a plurality of base stations, the algorithm applies RLS blind source separation and recovers the source signals of ADS-B, thereby improving signal decoding accuracy and the dynamic performance monitoring for aircraft. The paper has verified the signal separation, including signals based on two level overlapped and three level overlapped and signals with noise, and verified the feasibility of RLS algorithm in ADS-B signal separation by MATLAB simulation test.
