摘　　要：受到海浪、海风和洋流等海洋环境干扰,航空母舰在海面上航行时会产生横摇、纵摇、升沉等摇荡。为了分析舰船摇摆对舰载机着舰引导雷达测量误差的影响,根据虚拟基线定位测量理论,建立了舰艇摇摆带来的误差模型量化公式。在测相位差变化定位中的某些关键技术被深入探讨,为舰载雷达天线指向误差计算及探测误差分析提供理论依据。仿真结果显示了算法的有效性。The ship will be in rocking in various directions,for example,the heave,the pitch and the roll,if ship is disturbed coming from waves,wind and ocean current.To analyze the effect of ship sway to detective error measurement,the quantitative formulas of error model were constructed based on virtual baseline.Some key technology is deeply discussed in phase difference locating,which provided a theoretical basis not only for the error detection but also for the calculation of radar antenna directivity.The simulation result verifies the effectiveness of the method.
