| 摘 要： | 利用二维静态方向图数值综合方法（Numerical Pattern Synthesis,NPS）同时对方位角和俯仰角进行优化，完成高频地波雷达回波信号的数字波束形成，并利用一种基于方向图旁瓣的性能模型来确定最优参数，实现电离层干扰抑制的功能. 对8×8元方阵的仿真分析及实测的回波数据分析发现，来自空中电离层干扰的影响明显减轻，从而证明了该方法的有效性.

| Abstract: | Numerical pattern synthesis(NPS) method is used to restrain the ionospheric interference in high frequency surface wave radar(HFSWR) system. Both horizontal and vertical directions are involved during beamforming. Proper parameters determined by a directional pattern performance model reveals better performance. The results for 8×8 array simulation and real data show that the ionospheric interference from sky can be effectively restrained. |
