Automatic Dependent Surveillance-Broadcast(ADS-B) signal receiver technology is studied for the design requirements of low-cost, high-performance ADS-B system. The ADS-B signal software receiver based on 1090ES mode is designed based on software radio technology. The design is verified with RTL-Software Defined Radio(SDR) and Matlab, realizing the actual reception of ADS-B signal for civil aviation flights. Compared with the traditional ADS-B receiver, it has the advantages of simple structure, high flexibility and high development efficiency.
