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。
Based on the ACLS, which is used in the conventional carrier-based aircraft, and the active radar guidance ship as the main guidance method, the influence of signal error in the radar guidance on the warship is analyzed. Based on the composition and function of a fully automatic ship-to-ship system, a complete system and environment for the ship-to-ship simulation is established. Three different types of errors, including radar signal measurements, time delays and noise clutter, are added to simulate the ship’s existence situation. The correctness of the result is verified by calculating the success rate of landing and its decreasing with the absolute value of the error magnitude. This method can quantitatively analyze the influence of radar signal error, which not only contributes to the study of the ship’s theory but also instructs engineering design and application.
