| 5. | Each mission had a satellite designed to photograph the surface of mars from orbit , and to act as a communication relay for the viking lander that each mission carried 每次任务都发射一枚具备从火星轨道拍摄火星表面能力的人造卫星,同时充当与海盗登陆者进行联络的中间站。 |
| 6. | 1 . the transfer architecture of the uav ' s blos communication is studied . based on the layered structure , we presented a new topic design of the uav platform based blos communications relay , which includes backbone layer , tactical layer and mission layer 研究了无人机超视距通信的传输体制,基于结构分层概念,提出了包括主干层、战术层和任务层的无人机超视距多链路中继的综合信息传输方案。 |
| 7. | Motivated by the increasing request of providing the battlefield data dissemination and communications relay , we presents the design of an unmanned aerial vehicle ( uav ) platform ' s applications of tactical communications for providing beyond - line - of - sight ( blos ) communications capability . providing a description of the uav platform ' s development , we conduct a deeply study on the wireless asymmetric data link structure , communication protocols and the algorithm of data dissemination 本文根据战场通信覆盖和数据分发的需求,用无人机作为超视距战术通信的中继平台,构成非对称数据传输系统,对系统体制、非对称传输链路、通信协议和数据分发调度算法等进行了深入研究。 |
| 8. | Coupling efficiency not only affects fiber communication relay distance , but also affects the performance of edfa and semiconductor light amplifier ( sla ) . so it is very important to improve coupling efficiency and reduce its cost . according coupling theory , the coupling of laser diode to single mode fiber is to meet the mode field diameter match and the phase match 它不仅直接影响光纤传输的中继距离,而且对改善ld泵浦掺铒光纤放大器( ldp - edfa ) , ld泵浦固体半导体激光器( ldp - ssl ) 、半导体光放大( sla )等光通信器件及系统的性能上,在提高他们的性价比有着十分重要的意义。 |
