摘　　要：基于窄带波束形成Olen-compton的思想,提出了一种恒定幅度宽带波束形成算法。该算法通过在主瓣区域加入虚拟干扰,对主瓣宽度进行调整,其目的是为了使各个频率的波束宽度不发生变化,实现束宽的恒定。仿真实验结果证明了通过在主瓣区域内加入虚拟干扰从而调整波束的主瓣宽度是切实可行的,因而可以应用于宽带信号的恒定束宽。The narrowband beam forming algorithm of Olen-compton is applied to the broadband beam forming,and a constant amplitude broadband beam forming algorithm is proposed in this paper. In the algorithm,the virtual interference is joined in the main lobe region of various narrowband signal to adjust the main lobe width,so as to maintain a constant beam width of each frequency,and reach a constant beam width. Simulation results show that the algorithm by joining the virtual interference in the main lobe region of various narrowband signal to adjust the main lobe width is feasible,and can be applied to the broadband signal constant beam width.
