摘　　要：针对宽带信号的波束形成问题,利用Olen和Compton的自适应窄带波束优化设计方法的原理,提出了基于Olen-Compton的恒定响应宽带波束形成算法。该算法利用DFT将宽带信号划分为若干窄带信号,通过在各个窄带信号的主瓣和旁瓣同时增加虚拟干扰,来调节窄带波束,使得当前波束与参考波束整体近似相等,达到恒定束宽的目的。计算机仿真实验结果表明,该算法实现了宽带信号的恒定束宽,达到了宽带波束形成的目的。With respect to the beam forming of broadband signals,the broadband constant response beam forming algorithm is pro-posed on the base of Olen-Compton algorithm by using the principle of adaptive narrow band beam forming optimization method of Olen-Compton. In the algorithm,DFT is used to divide the broadband signal into a number of narrow band signals,then virtual interference is added to the main- and side-lobe of various narrowband signals to regulate the narrow beam,so as to keep the beam approximately equal to a reference beam integrally and achieve a constant beam width. Computer simulation results show that the proposed algorithm achieves a constant beam width of broadband signal and realizes the purpose of broadband beam forming.
