摘要
在运用模匹配法和球面波展开法分析和设计紧凑式波纹喇叭的基础上，首次提出了对紧凑式波纹喇叭进行容差分析。并以某星载紧凑式波纹喇叭为例，给出了容差变化对交叉极化和回波损耗的影响，为设计紧凑式波纹喇叭提供了重要的参考依据。
Based on the analysis and design of compact corrugated horn by using the mode matching method and spherical wave expansion,the tolerancing analysis of compact corrugated horn is presented for the first time in the paper,and taking the on board compact corrugated horn for an example.The paper gives the effect of tolerances of design parameters on the cross polarization and return loss of compact corrugated horn and provides the important criteria for designing compact corrugated horn.
