Design of TT&C and Information Transmission System Based on a Model Free Flight Test

摘要:

针对模型自由飞试验的技术要求,设计了某模型自由飞试验使用的测控与信息传输系统,针对系统设计要点突破了多项关键问题,给出了系统关键点的设计方法和具体实现过程,并结合实例和仿真给出了相应的结果,通过地面试验对整个测控与信息传输系统的性能进行测试,包括地面及机载收发信机的接收灵敏度测试、系统时延测试等,试验结果表明,收发信机接收灵敏度及链路延时等指标都能满足模型自由飞试验的要求;对同类型系统设计有重要参考价值。

Abstract:

According to the technical requirements of free flight test, a tracking,telemetery and command(TT&C) and information transmission system used in model free flight test is designed. A number of key issues are broken through according to the system design requirements. The key design method and implementation process of the system are presented. The performance of the TT&C and information transmission system is tested through the ground test,including the receiver sensitivity performance test, the system delay performance test, and other kinds of performance tests. The test results show that the receiver sensitivity and link delay can meet the requirements of the model free flight test. It has an important reference value to the same kind of system.
