舰艇卫星通信天线遮挡问题研究

Research on Blocking Problems of the Satellite Antenna of Warships

由于舰艇空间相对狭窄,卫星天线存在被本舰艇上层建筑遮挡而导致通信困难的问题。在分析卫星通信俯仰角、方位角计算方法及解析法航法计算的基础上,结合舰艇横、纵摇对卫星通信天线影响方式,研究舰艇上层建筑对卫星天线遮挡区域及对应经纬度计算方法,得出避免卫星通信天线遮挡的通信规划及舰艇机动对策措施,对于做好舰艇卫星通信保障具有较为现实的意义。

Because of narrow space,the satellite antenna of warships is easy blocked by the superstructure.The blocking problems can make satellite communication difficulty.Based on the analysis of computational methods of the angles of pitching,bearing and navigation, and according to the effect of pitch and row on the satellite antenna of warships,this paper studies the computational methods of blocking areas of the satellite antenna and corresponding longitude and latitude,then the methods of the satellite communication planning and maneuvering of warships for avoiding blocking problems are put forward.It is important for us to enhance the satellite communication.
