中文摘要： 多模复合制导系统具有作用距离远、制导精度高、命中概率高等优点,得到愈来愈广泛的应用，成为未来精确制导武器的发展方向，而复合双频单脉冲天线是决定其性能最关键的部件之一，目前国内关于共面单脉冲双频天线的研究基本上属于空白。本课题的创新点是发展一种采用创新的边馈馈电方式和小型化天线单元来实现共面单脉冲双频天线阵，并采用一种先进的馈电网络设计来改善两频段之间高次模影响。本课题组已研制出振子/波导、波导/波导两种单脉冲双频单脉冲天线阵样机，已经申请了一项国防专利。目前我们在充分预研的基础上，有了更先进的创新思路，相信可取得具有国际先进性的研究成果，为我国后续相关复合制导研究提供技术储备.

英文摘要： Dual mode compound guidance system has many advantages, such as long distance, high-precision and high hit probability ,which has wide application foreground and becomes the precision-guided weapon development orientation in future. Compound monopulse dual-frequency antenna array is the key component and decides the performance of dual mode guidance system. Now the co-aperture monopulse dual-frequency antenna array is rarely studied .The innovation of our research topic is to realize a new co-aperture monopulse dual frequency antenna array with a novel side-feeding method and a new compact antenna ,which at the same time uses an advanced feeding network to decrease the higher-order mode effect .Our research group has studied and manufactured two types of monopulse dual-frequency antenna array, which are applying for defence patents .Now based on the study beforehand ,with our more innovative idea we believe a research production of international advanced level will be obtained ,which can provide technical reserve for related research on dual mode compound guidance system in future .
