Design and implementation of a novel high-sensitivity double mode ADS-B digital receiver

Related automatic dependent surveillance(ADS) is one kind of Air Traffic Control(ATC) surveillance technology has been well developed by the international civil aviation organization. In order to satisfy both management and monitoring of the general aviation and commercial aviation, the system uses 1090 ES and UAT double data link mode system model to. This paper puts forward a kind of ADS-B digital receiver system design scheme based on the 1090 ES and UAT data link. Using ADS simulation software, the RF front-end system, power splitters and low noise amplifier modules are simulated. Then this paper verified these modules through the way of multi-module converter and making the sheet of the PCB. At last, the field test verifies the effectiveness of the receiver, and achieves higher receiver sensitivity, dynamic range and other technical indicators.
