一种高任务可靠性雷达架构设计

Architecture Design for High Mission Reliability Radar

场面监视雷达被用于机场监视和为机场交通管制的可靠工具,需要具有极高的系统任务可靠性以保证机场的安全运行。针对一种场面监视雷达的设计需求,通过分析系统中分机以及模块的薄弱环节,提出了一种高任务可靠性的混合冗余设计架构。可靠性建模和分析计算表明,基于该架构设计的场面监视雷达能够安全执行机场保障任务。

As a reliable tool for airport surveillance and airport traffic control, surface movement radar （SMR） should have high system mission reliability to ensure the safety of the airport. Aiming at the requirements of a SMR, a high mission reliability mixed redundant architecture design is proposed by analyzing the weakness of the LRU and the module. The reliability modeling and analyzsing indicate that SMR with proposed architecture can accomplish the airport safeguard mission safely.
