摘　　要：为了有效降低阵列波束中的旁瓣,抑制旁瓣区域的干扰信号,提出一种基于二次组阵的低旁瓣波束形成的修正算法。理论分析与计算机仿真结果表明,该方法与常规LCMV方法相比,既能深度抑制干扰信号,又能有效地降低方向图中的旁瓣水平,大大提高了系统的抗干扰能力。In order to reduce the sidelobe level of the pattern for the array antennas and restrain interference signal in side- lobe region, this paper presents a modification algorithm for low-sidelobe beamforming based on secondary combination of the array antennas. Theoretical analysis and computer simulation results show that, compared with the LCMV method, the method based on secondary combination of array can deeply restrain interference signal, effectively reduce the sidelobe level of the pattern and great- ly improve the system＇s performance of anti-interference.
