采用分布式频率源已经成为雷达系统设计中的一种发展趋势。分布式频率源体制改变了雷达阵面组成及功能任务剖面,进而对频率源可靠性分析提出了新的要求。文中以频率源分布化后的影响为例,在满足阵面重大故障平均间隔时间(MTBCF)要求的前提下,分析了相较于集中式频率源体制,分布式频率源体制对频率源模块平均故障间隔时间(MTBF)的要求。通过该文分析,能够对分布式频率源的可靠性设计提供指导建议。

Distributed frequency source has become a development tendency in radar system. The design of distributed frequency source changes the form and mission profiles of radar antenna, and proposes reliability analysis requirement of frequency source.On the condition of satisfying the antenna MTBCF requirement, this paper analyses the MTBF requirement of distributed frequency source compared with single frequency source. This paper can contribute to the reliability design of distributed frequency source.
