提出一种将传统比例导引和模糊制导相结合的融合制导方案，依靠比例导引部分保持制导系统对探测信息噪声的鲁棒性。利用模糊逻辑制导部分增强制导系统对拦截条件的自适应变化能力，通过融合形成最后的制导指令，使得比例导引和模糊逻辑制导的良好特性均得到发挥。仿真结果表明，这种制导方法精度高，性能优良。

Fuzzy Logic Based on High Performance Fusion Guidance

A high performance fusion guidance approach is presented. The guidance algorithm is composed by three parts, including traditional proportional navigation, fuzzy logic based guidance and a guidance fusion unit. Fuzzy logic based guidance is a proportional navigation with effectiveness navigation ratio adjusted with fuzzy logic using measured LOS rate and closing speed as inputs. The fusion unit combines the proportional navigation and fuzzy logic based on guidance commands together to give the final guidance command through weighted-fusion method. The guidance performance is compared with proportional navigation. The results demonstrate that the new guidance law is of high guidance precisions.
