摘　　要：对误差分布函数进行了理论分析,通过分析有源相控阵系统的组成,构建了其误差组成结构,并推导了误差计算公式。通过理论推导和仿真分析研究了幅相误差对有源相控阵天线副瓣电平的影响。结合误差计算公式和副瓣电平公式得到了实现所需副瓣电平的幅相误差分配方法。The error distribution function is analyzed theoretically, the error composition structure is created by analysis. The composition of the active phased array system and the formulas of amplitude and phase error calculation are derived. The effects on side-lobe arrays of amplitude and phase errors in the active phased array are researched by theory and simulation. Amplitude and phase errors distri- bution of the design antenna sidelobe are received by cotnbining the error calculation formulas and an- tenna sidelobe formulas of amplitude and phase errors.
