| 摘 要： | 直升机进行卫星通信,通信信号将受到旋翼遮挡的影响,信号质量将会下降,严重时会造成信号中断。提出了一种直升机旋翼缝隙检测方法,以确定"通信窗口",在旋翼缝隙期间,信号进行发射;在旋翼遮挡期间,信号不发射;地面设备接收信噪比通过前向链路反馈给机载设备,机载设备可实时调整"通信窗口"大小,提高了缝隙利用率。

| Abstract: | The communication signals are affected by the blockage effects from the rotor in satellite communication system on the helicopter.The quality of signals is declined, and the signals are interrupted in some serious cases.A detection method of blade slot for helicopter satellite communication is described in this paper for ascertaining the ＂communication window＂.In the period of blade slot, the signals can be emitted, and in the period of blade shade, the signals can＇ t be emitted. By returning Signal-to-Noise of ground equipments received to helicopter equipments, they can adjust the length of ＂communication window＂ simultaneously, thus it improves the utility ratio of the slot. |
