再入遥测三维空间分集接收的设想与实现技术

The Idea of Three-dimensional Space Diversity Reception of Reentry Telemetry and Its Implementation Technology

为了可靠接收大型武器飞行试验中的再入遥测信号,减小电波传输多径效应的影响,在空间分集接收现状的基础上,提出在场区布设空间站实现对信号三维空间分集接收的设想。分析了设想的可行性,评估了效果,并就设想如何实现研究了空间站飞行控制、分集数据传输与合并等技术。最后,对设想向实践转化时应注意的一些问题进行了强调,提出了要求。

In order to receive the reentry telemetry signal of large weapons＇ flight test reliably and reduce the impact of multipath effects of radio wave transmission, based on the status of the space diversity receiver, an idea to diversity receive signal in three-dimensional space by disposing the space stations in the range is proposed. The feasibility of the idea is analyzed and the effect is assessed. Then the space stations＇ flight control and diversity data transmission and merge are studied to realize the idea. Finally, some problems which should be paid attention to during the transformation from the idea to practice are emphasized, and some requirements are set.
