全自动着舰引导对于提升海上作战效能至关重要。然而，由于技术手段、设备配备以及通信链路的单一化，传统的全自动着舰引导系统故障容限低，难以有效保障着舰过程的飞行安全。针对系统可靠性和安全性较低的问题，深入分析功能危险性和安全设计需求，优化系统余度结构。基于导航技术冗余构建引导信息多余度测量结构，基于链路冗余和余度计算机构建引导指令多余度解算结构，同时基于多种助降手段和监视设备构建指挥辅助决策多余度保障结构。对多余度全自动着舰引导系统进行故障树分析，评估多余度系统每小时危险失效概率，以验证系统的高可靠性和高安全性。

The automatic carrier landing guidance system is crucial for enhancing the effectiveness of naval operations. However, due to the singular nature of technical methods, equipment configuration, and communication links, the traditional auto-matic carrier landing guidance system exhibits a low fault tolerance, making it difficult to ensure flight safety during the landing process. To address the issues of low system reliability and safety, an in-depth functional hazard analysis and safety design requirements is conducted to optimize the system’s redundancy architecture. A multi-redundant measure-ment structure for guidance information is constructed based on redundant navigation technologies, while a multi-redundant calculation structure for guidance commands is built using link redundancy and redundant computers. Addi-tionally, a multi-redundant decision-making safeguard structure is established by integrating various landing aids and monitoring equipment. Fault tree analysis is performed on the multi-redundant automatic landing guidance system, and the probability of dangerous failure per hour is evaluated to verify the system’s high reliability and safety.
