摘　　要：以孤立缝隙的理论为基础,应用仿真技术与数据处理方法综合分析了缝隙和波导参数的误差对缝隙导纳特性的影响。在线阵中根据随机误差分析相关理论,综合考虑包括缝隙和波导参数在内的多个结构参数的误差对阵列幅相分布影响的不同作用率,对误差进行了合理的分配。最后以某毫米波频段波导缝隙线阵天线为例进行分析,并以软件仿真进行验证。Based on isolated slot theory, simulation technique and data processing method are applied to analyze the effects of slots and waveguide parameter errors on admittance characteristics. According to the related theory of random error analysis in the linear array, the different effect ratios are considered, including the effect of errors of slots and waveguide multi - structural parameters on the amplitude and phase distributions. And the reasonable tolerance distribution is performed. Finally, an example of waveguide slot linear arrays at millimeter wave band is analyzed and validated by the electromagnetic software.
