摘要
射频传感器系统是航空电子系统的重要组成部分,综合化、模块化是射频传感器发展的必然趋势。重构设计正是随着航空电子综合化技术的发展和提高任务可靠性的需求应运而生的,已成为模块化综合射频传感器系统的关键技术之一。对射频传感器系统常用的两种不同重构方式,即基于模块重构和基于通道重构的设计和实现进行了阐述,在此基础上,运用可靠性理论对两种重构方式进行了建模,对其平均故障间隔时间(MTBF)进行了详细的计算、分析和比较,最后给出了比较结果。
RF sensor system is one the most important components of the avionics.Integration and modularization are inevitable trends in the RF sensor system.Reconfigurable design emerged with the development of integrated technology and requirement of high reliability in the avionics.It is becoming one of the key technologies in the integrated modular RF sensor system.Two different reconfiguration methods are expounded on,one is based on modular-reconfiguration and the other is based on tunnel-reconfiguration.With the help of reliability theory,modeling of the two methods as well as,calculation,analysis and comparison of MTBF are proposed.
