摘　　要：对Ｓ波段超低副瓣阵列天线中的线阵和面阵的相关误差、非相关误差与平均误差副辨电平、最大误差副辨电平之间的各种关系进行了分析，得到了一些有用的公式和图表。实验证明水平（Ｅ）面在３００ＧＨｚ内最大副瓣电平低于－４０ｄＢ，宽角副瓣电平低于－５０ｄＢ，垂直（Ｈ）面内在中心频率处最大副瓣低于－３８．７ｄＢ，交叉极化最大副瓣电平低于－４０ｄＢ。Some useful formulations,figures,tables,and some relations are given in this paper.It includes the relations between the Max sidelobe level,the related errors,unrelated errors, the mean value and the max value of the error sidelobe level,the linear and the planar array antenna.By demonstrated,the Max sidelobe is lower than -40dB in the 300 MHz band,the mean value of the sidelobe is lower than -50dB in horizon.On the center frequency,the Max sidelobe is lower than -38.7dB in vertical. The Max sidelobe of cross polarization is lower than -40dB.
