Performance analysis for terrestrial radio waveform for control and non-payload communication of unmanned aircraft systems

摘要

Necessity for interoperable control and non-payload communication technology and system deployment is increased for safe unmanned aircraft system (UAS) operation as well as extension of UAS applications. For this, C-band frequency was globally allocated only for CNPC in world radio conference 2012 (WRC-12). The technology development and standardization activities for high reliable UAS CNPC operating in the C-band frequency has already been kicked off in US and efficient radio communication technologies are being considered with respect to the size, weight, power and cost (SWaP-C) of UAS. In this paper, we analyze the terrestrial radio waveform standardized in radio technical commission for aeronautics (RTCA) and make some proposals for its performance enhancement.
