| 摘要: |
| 目前用于机载前舱卫星通信的L频段终端系统设备，全部是由国外厂商提供，且多采用平面阵或机械扫描的方式。提出“屋顶”形天线阵列来实现超低仰角覆盖，设计并研制了L频段机载前舱卫通相控阵天线样机。地面静态对星试验结果表明，天线样机可与海事卫星实现稳定通信，通信速率为310 kb/s，通信质量良好。相比于以往的平面布阵或机械扫描方案，这是一种规模小、重量轻的低仰角覆盖方法，非常适用于L频段机载前舱卫通天线。 |

| Abstract: |
| All the currently-used L-band terminal system equipment for airborne forward compartment satellite communication is provided by foreign manufacturers,and most equipment adopts planar array or mechanical scanning mode,which has no advantages in size and weight.The “roof” antenna array is proposed to achieve ultra-low elevation coverage,and the L-band airborne forward hatch satellite phased array antenna prototype is designed and developed.The results of ground static correspondence experiment show that the antenna prototype can realize stable communication with the maritime satellite.The communication rate is 310 kb/s,and the communication quality is good.Compared with the previous planar array or mechanical schemes,the proposed method is a low-elevation coverage method with small scale and light weight,which is very suitable for the L-band airborne forward hatch antenna for satellite communications. |
