摘要
设计了一种基于时分双工协议的单载波频带靶机测控系统,在机载和地面站均只配备一套数传电台的情况下,实现全双工通信。详细介绍了时分双工(TDD)协议的帧结构、帧同步和通信实现,并以某型靶机为例分析和计算测控通信的需求和性能,经性能计算和分析表明,该通信协议科学可行。
A single carrier frequency band target drone measurement and control system based on Time Division Duplex(TDD)protocol is designed to realize full Duplex communication when only one digital transmission station is equipped on both airborne and ground stations.The frame structure,frame synchronization,and communication realization of TDD protocol are described in detail.The requirement and performance of drone aircraft are analyzed and calculated.,the results show that the communication protocol is scientific and feasible.
