导重法是一种融合了理性准则法和数学规划法优点的准则法，它考虑到了随截面变化而引起的含重量在内的外载荷变化的影响等突出优点，适用于大型、复杂结构的优化设计，特别是需要利用有限元法进行性能约束计算的优化设计。将其运用于某雷达天线阵面的动力优化设计中，并采用ＳｕｐｅｒＳＡＰ９１有限元软件作为有限元分析的工具，取得了较为满意的结果。
Guidance law is a combination of the principles of the law of law and mathematical programming method of merits of the law, which takes into account the changes with the cross section, including weight, including the impact of changes in the load and other prominent advantages for large and complex structures Optimize the design, especially the optimization design that needs finite element method to calculate the performance constraint. Applying it to the power optimization design of a radar antenna array, and using SuperSAP91 finite element software as the tool of finite element analysis, the satisfactory results have been obtained.
