摘　　要：为分析光纤制导导弹飞行中光纤信道变化情况,满足导弹动静态仿真需求,设计了一种能够模拟光纤数据链路传输损耗特性的装置。研究内容包括建立系统传输损耗的动态、静态模型。利用光模拟器实现导弹飞行中可能遇到的信道干扰、数据延迟、动态损耗等情况。实验结果表明,光信号干扰的变化范围达到-50dBm^-40dBm,光信号的传输延迟范围为16.65μs^99.9μs,模拟器动态损耗调整范围为0dBm^50dBm,可用于验证导弹光纤传输系统的性能。In order to analyze the fiber changes of the optical-fiber guidance missile in flight and meet the needs of the missile static and dynamic simulation,a device that can simulate data link transmission loss characteristics of optical fiber was designed.The dynamic and static models of system transmission loss were established.Using the optical simulator,the channel interference,dynamic loss,data delay,etc,that may occur in the missile flight were implemented.The experiment results show that the interference range of optical signal is-50dBm^-40 dBm,the delay range of optical signal transmission is 16.65μs^99.9μs,the adjustment range of simulator dynamic loss is 0dBm^50dBm.The performance verification of optical fiber transmission system can be realized.
