The Preliminary Investigation of Communication Characteristics Using Evaporation Duct across the Taiwan Strait

Affected by the Taiwan Strait Warm Current, evaporation intensity around is significantly higher than in other southern and eastern coastal areas of China. To explore a new effective method for maritime communication across Strait, we present preliminary investigation wireless microwave transmission an duct. From 9 to 14 o’clock, percentage duct height exceeding 10 m reached over 90% 2020. With favorable channel this period, “straight-through propagation channel” emerged, with serviceable ratio 99.00% at 300 km range. The high-quality BPSK modulation occurred 98.90% year from 12 13 89.89% signal-to-noise (SNR) 90 dB. Based on use duct, proposed can provide support applications Strait.
