摘　　要：针对新一代防空雷达论证中搜索工作模式设计问题,首次从理论上系统地推导了数字阵列雷达俯仰波位编排解析式,并给出了传统设计搜索时间资源分配设计。指出在数字阵列雷达搜索工作模式设计中,单一的波束形状设计不能发挥数字阵列体制带来的优势,提出了采用低角笔形、高角赋形对时间资源进行优化设计,理论推导了笔形和赋形之间的分界角以及优化后的时间资源分配过程,优化后搜索时间资源利用率将大幅提升。最后通过计算机仿真和实例应用验证了文中方法的有效性。该方法对新一代防空情报雷达、目标指示雷达、制导雷达论证具有重要意义,同时对现役防空雷达数字化升级改造具有一定指导意义。Aiming at the search working mode design in the demonstration of new generation air defense radar,for the first time,the analytical formula for the pitch beam arrangement of digital array radar is derived systematically in theory,and the search time resource allocation process of traditional design is given accordingly.It is pointed out that single beam shape design cannot take advantage of digital array system in the design of search working mode of digital array radar,therefor a method by using pencil beam for low elevation and shaped beam for high elevation is innovatively proposed to optimize the design of time resources,the pitch dividing angle between pencil beam and shaped beam and the optimized time resource allocation process are theoretically derived.The utilization of optimized search time resource will be greatly improved.Finally,the effectiveness of the proposed method is verified by computer simulation and case application.The conclusion is of great significance to the demonstration of the new generation air defense intelligence radar,target indication radar and guidance radar.At the same time,it also has certain guiding significance for the digital upgrading of the active-duty air defense radar.
