摘　　要：针对在二维平面相控阵天线和椭球天线罩之间增加引向天线会使天线阵列的辐射相位中心由二维扩展到三维,经典的平面相控阵波束控制算法不再适用的问题,基于高增益引向天线阵列,提出一种三维阵列的波束控制算法,在机相扫模式下修正脉间波束指向,提高波束扫描精度,并给出了工程实现的具体流程,最后通过地面测试验证了新算法的性能优势,并通过空中配试靶机验证了新算法的探测性能。Adding a directional antenna between a 2D planar phased array antenna and an ellipsoidal antenna radome extends the radiation phase center of antenna arrays from 2D to 3D,which renders classical planar phased array beam-steering algorithms no longer applicable.Based on a high-gain directional antenna array,a beam-steering algorithm for 3D arrays is proposed.The algorithm corrects interpulse beam pointing in the mechanical and phase scanning mode,thereby enhancing beam scanning precision.A detailed engineering implementation process is provided.Finally,the performance advantages of the new algorithm are validated through ground testing,and its detection capabilities are confirmed through airborne target trials.
