      Effect of radar signal error on automatic carrier landing control of carrier-based aircraft

      摘要:
      基于常规舰载机使用的全自动着舰系统(ACLS),以及现役的作为主要导引方式的雷达导引着舰,分析了雷达导引过程中的信号误差对着舰的影响.从全自动着舰系统的组成和作用出发,建立完整的着舰仿真系统与环境,加入雷达信号测量数值、时间延迟和噪声杂波干扰3种不同类型的误差,以仿真误差存在时的着舰状况.通过计算着舰成功率,及其随误差量值的绝对值增大而减小的特点,验证了结果的正确性.该方法定量分析雷达信号误差的影响,既有助于着舰理论的研究,也对工程设计和应用具有指导意义.
      Abstract:
      The effect of signal error on carrier landing during radar navigation was analyzed based on the automatic carrier landing system (ACLS) of natural carrier-based aircraft and the commissioned main guiding way of radar navigation in carrier landing.According to the components and the functions of the ACLS,the system and the environment of the whole carrier landing simulation were established,and three different kinds of radar error including testing value,delay time and noise were taken into simulation in order to simulate the landing conditions with error.The results were proved correct due to the calculation of carrier landing success rate which became lower as the absolute value of error increased.This method analyzes the effect degree of radar signal error quantitatively,which not only contributes to the study of carrier landing theory,but also possesses guiding significance for engineering design and application.
