摘　　要：针对雷达引导架构下自动着舰流程,根据自动着舰典型场景与着舰引导雷达参数,详细分析了雷达引导定位的测量误差成因、误差类型、误差量级;计算得到的雷达定位测量精度与公开的AN/SPN-42雷达部分性能一致。设计了机上引导自动着舰系统架构并构建了基于F/A-18A舰载机的全自动着舰仿真,引入雷达引导误差、自动着舰系统延迟、舰尾流、甲板运动和机载传感器噪声干扰因素。通过统计着舰点偏差标准差衡量着舰性能,结合回归分析定量刻画了干扰因素对最终着舰结果的影响。结果表明,甲板运动幅度对着舰点偏差标准差具有最显著作用。According to the typical scene of automatie landing and the parameters of landing guidanceradar,the causes of measurement errors,error types and error magnitude of radar guidance positioning areanalyzed in detail.The caleulated accuracy of radar positioning is consistent with the perforance of thepublished AN/SPN-42 radar,The architecture of Automatic Carier Landing System(AClS)is designedand the simulation of the system based on F/A-18A aireraft is constnucted.The disturbanee faetors of radarguidance eror,automatic landing system delay,carrier air wake,deck motion and airbore sensor noise areintroduced.The touchdown point standard errors are calculated by mumerieal experiment to illustrated thelanding performance.and the influence of disharbanee factors on landing results is quantitatively deseribedby regression analysis.The results show that the amplitude of deck motion has the most significant effect onthe standard deviation of touchdown point.
