Addressing vulnerabilities of the CNS infrastructure to targeted radio interference

摘要

Communication, navigation, and surveillance (CNS) technology is the backbone of modern-day air traffic management (ATM), containing a wide variety of radio systems that include ground stations, satellites, and aviation users. With the continuing development of software-defined radio, CNS systems are faced with a fundamentally new challenge that was not known at the time many of the systems were designed: software-defined radio has simplified the generation of radio signals with arbitrarily configurable modulation schemes and waveforms, to the point in which it has become financially accessible for private individuals.
