摘要
探讨智能蒙皮天线分布式设计总体方法,采用结构功能一体化天线设计技术,实现智能蒙皮天线的子阵单元设计,然后研究空天飞行器的智能蒙皮天线分布式布局、分布式体系架构以及功能实现。最后探讨智能蒙皮天线分布式波束综合方法,通过合理调用智能蒙皮天线子阵单元数和多空天飞行器联合资源整合,实现智能蒙皮天线的波束自适应;每个子阵单元均采用方向图可重构技术,实现智能蒙皮天线的高增益宽角域扫描,解决经典相控阵天线在大扫描角度上阵列增益损失过大的缺陷;在宽带分布式阵列波束合成上,采用基于数字延时的子阵波束合成方法,解决智能蒙皮天线分布式波束合成与对准。这些方法为进一步研究智能蒙皮天线奠定了技术基础。
The overall distributed design methods of smart skin antennas are discussed in this paper.The structure-function incorporate antenna design technique is used to realize the subarray unit design of smart skin antennas.The distributed layout,distributed system structure and function implementation of smart skin antennas of aerocraft are researched.The distributed beam synthetic method of smart skin antennas is discussed.The number of subarray cell of smart skin antennas is called reasonably and the joint resources of multi-aerocraft are integrated to realize the beam adaption of smart skin antennas.The pattern reconfigurable technique is adopted in each subarray unit to realize the high gain and wide angle scanning of smart skin antennas,and reduce the array gain loss of classical phased-array antenna within large scanning angle scope.The subarray beamforming method based on digital delay is used for wideband distributed array beamforming to realize the distributed beamforming and alignment of the smart skin antennas.These methods lay a technique foundation for further studying the smart skin antennas.
