散射通信技术是利用通信波束在高空10～12 km以下对流层中产生的散射现象进行通信的一种通信方式,其单跳传播距离远、传输容量大、传播信道可靠稳定,被广泛用于中远距离无线通信中。由于海岛通信对通信信道和通信设备的特殊要求,近年来随着散射通信技术的日趋成熟,散射通信开始大量应用于海岛无线通信中。从海岛散射通信的理论依据、关键技术和端站建设要求三个方面对海岛散射通信进行了分析。
Scatter communication technology is a communication mode that uses the communication beam to transmit the scattering phenomenon generated in the troposphere at a height of 10 to 12 km. The single-hop propagation distance, the large transmission capacity and the reliable and stable propagation channel are widely used in long-range In wireless communication. Due to the special requirements of communication channel and communication equipment in island communication, as the technology of scattering communication becomes more and more mature in recent years, scattering communication has been widely used in the island wireless communication. This paper analyzes the island scattering communication from three aspects: the theoretical basis, the key technology and the requirements of the terminal building.
