以弹载共形相控阵雷达导引头天线为应用背景，将共形天线技术与自适应阵列处理技术相结合，通过欧拉坐标变换，建立了基于有向阵元的锥面共形天线阵列方向图模型，应用了一种基于最大信噪比准则的自适应算法对锥面天线阵列进行了方向图综合。该算法通过对副瓣区域干扰信号的迭代得到一组最优复加权矢量，仿真结果表明该算法可以在三维空间实现对主波束指向以及副瓣电平的控制。

Based on the application of seeker conformal phased array,the technique of conformal array and adaptive theory is used,the conical conformal directional element array is modeled by euler coordinate transformation,a adaptive algorithm based on the formulation of maximum signal-to-noise ration is used to synthesize the conical array pattern. A optimal complex weighted excitation is achieved by the interaction of interfering signals in sidelobe region,the simulation result shows that the mainlobe direction and the sidelobe level can be controlled in the 3D region.
