Design of an ADS-B Signal Receiver Based on Software Defined Radio

Abstract: In order to obtain track information in a timely manner, a software defined radio receiver system for Automatic Dependent Surveillance-Broadcast (ADS-B) signals is designed based on the RF front-end chip AD9361 and the baseband data processing chip Zynq-7000. A detailed hardware framework design is provided, a Linux platform is established, and the AD9361 register configuration work is completed. Tests show that when the signal-to-noise ratio exceeds 6 dB, the detection probability of the receiving system exceeds 60%; during actual
