In view of the difficulties in conducting innovative researches on highly integrated automatic dependent surveillance-broadcast (ADS-B) experimental platform, an ADS-B signal transceiver system was designed based on software defined radio platform. First, self-defined GNU Radio blocks named ADS-B encoder, baseband signal generation, preamble detection, ADS-B demodulator and ADS-B decoder were written in modifiable form. Then flow-graphs of ADS-B transmitter and receiver were created to realize the transmission and reception of ADS-B signal by using HackRF, which is a software defined radio peripheral. Finally, experiments were carried out to test the function and interface of each block. The results show that the design scheme is feasible, ADS-B signal format and message broadcast rate are compliant with the Do-260B standard. The receiver sensitivity is -68 dBm, and signal detection rate reaches 89%.
