摘　　要：以弹载多模复合制导雷达导引头为应用背景,在未考虑极化的情况下,首先建立了任意有向阵列的方向图函数;然后,采用同心圆等角度、同心圆等间距以及矩形栅格3种不同配置方式,建立了锥面共形相控阵天线模型,推导了不同配置方式下天线阵列方向图函数;通过比较其方位面及俯仰面的副瓣电平,得出结论:同心圆等间距配置方式是锥面共形相控阵雷达导引头天线单元的最优配置方式。Based on the application of seeker conformal phased array, a method of arbitrary conformal antenna pattern transformation from global coordinates to local coordinates was given firstly without the consideration of polarized information, and the expression of arbitrary array pattern was given. Then three different conical conformal array with the configuration of equal angle, equal distance and rectangular gird were modeled, the equal distance configuration was considered as the optimal configuration of conformal phased array seeker by the comparison of sidelobe of azimuth and elevation plane.
