摘　　要：针对大口径、高响应和低副瓣类雷达天线结构的设计难点,尝试突破传统设计方法瓶颈,建立一种基于TRIZ理论的设计方法,实现创新设计。该设计流程主要包括概念阶段的构型拓扑优化、工程设计阶段的试验设计(DOE)、验证阶段的仿真优化和试验测试。以某大口径高精度航管雷达天线为应用对象,首次实现了5 500mm×3 047mm碳纤维A夹层复合材料反射面的设计与制造,并最终实现天线型面精度0.65mm(rms)和天线系统设计减重50%。Aiming to the design difficulty of radar antenna structure with large diameter,high response and low sidelobe characteristics,a new design method that breaks through the traditional technique is proposed.The design method is based on the TRIZ theory and the innovation is achieved.The design flow mainly includes the topology optimization of configuration in the concept step,the design of experiment（DOE）in the design step,and the simulation optimization and experimental test in the validation step.With the proposed method,a large-diameter and high-precision of an air traffic control radar antenna is made as the study object.The design manufacture of 5 500mm×3 047 mm reflective surface with the carbon fiber A sandwich composites are realized for the first time.The precision of reflective surface reaches 0.65mm（rms）,and the weight of the antenna system reduces by 50%.
