摘要

Troposcatter is a promising candidate for beyond-line-of-sight (b-LoS) links because it can provide near-instantaneous point-to-point communication at distances of up to 300 km with high reliability. However, troposcatter communication is an underdeveloped research area. In this article, we review the channel modeling techniques for troposcatter. Most importantly, we analyze the coherence time and coherence bandwidth of troposcatter links for mobile receivers for the first time in the literature. In addition, we review the diversity techniques for troposcatter channels by outlining open research problems and possible application areas.
