舰载散射通信自主建链研究

目前主流的散射通信建链方式均依靠第三方通信手段,如果在强对抗环境中,无法进行双方站点位置信息的交换,散射通信将无法进行。针对这个问题,文章提出了 1种舰载散射通信的自主建链方法,利用不同波束宽度的天线以不同角速度进行空间扫描来完成建链。在建链过程中,主站采用步进式扫描,从站采用连续快速扫描进行目标站台方位搜索。仿真结果显示:岸-舰散射通信系统可以在几秒内快速完成建链；舰-舰散射通信系统由于双移动特性,建链时间会比较长,但也可以控制在分钟级。此方法在理论层面验证了散射通信系统自主建链可行性。

Autonomous Link Creation of Ship-Borne Troposcatter Communication

At present, the mainstream scattering communication link creation methods rely on other communication means. If the location information of the two sites cannot be exchanged in the strong confrontation environment, the scat-tering communication will not be carried out. To solve this problem, an independent link creation method for shipborne scatter communication is proposed. This method uses antennas with different beamwidths to carry out spatial scanning at different angular speeds to complete the link creation. In the process of chain construction, the master station adopts step scanning, and the slave station adopts continuous rapid scanning to search the orientation of the target station. The simula-tion results show that the shore-to-ship scattering communication system can quickly construct the chain in a few seconds. The ship-to-ship scattering communication system will take longer time to build the chain because of the dual movement characteristics, but it can also be controlled at the minute level. This method verifies the feasibility of independent chain construction of scatter communication system in theory. If it is verified in practical system, it can make the army take the initiative in the complex war environment.
