摘　　要：平板裂缝天线具有高增益、低副瓣、体积小、质量轻的优点,在机载雷达领域得到广泛的应用。针对某机载雷达天线面阵的研制而提出。根据该天线单面阵结构特点,分析了天线的馈电腔和辐射板的制造工艺要点。并重点从精确定位方式、精密加工装夹设计、误差分配和补偿方法、高速加工工艺设计以及仿真分析等几个方面入手,提出相应解决方案。该方案经实践证明切实可行,对类似的天线研制具有一定借鉴意义。The plate slotted - array antenna is widely applied in the airborne radar field, with the advantages of high gain, low side - lobe, small volume and light weight. In view of the development about the certain airborne radar antenna array, considering the structural features of antenna array, analyse the cruces in manufacturing of feed cavity and radiant plate, and present the corresponding solution by mainly dealing with precise positioning style, delicate clamp design, error distribution and compensation method, high speed machining technology design, machining simulation and program optimizing. This scheme is proved feasible by practice, which can be used for reference in development of the similar antenna array.
