Radio waves are highly attenuated and distorted by turbulent plasma sheath around hypersonic vehicles in near space, leading to communication blackout. The purpose of the paper is to investigate the plasma channel characteristics and the communication performances over the channel. We treat the turbulent plasma medium as a fast fading wireless channel. The coherence time and the spectrum spread of...
The plasma sheath surrounding vehicles traveling at hypersonic velocity absorbs and distorts electromagnetic (EM) waves, resulting in communication blackout. Unlike traditional multi-path channels, the plasma sheath channel is determined by plasma turbulence and its interactions with EM waves. A new channel model for turbulent plasma sheath is proposed, which is highly parameterized for the convenience...
