摘　　要：步进频率信号作为一种宽带信号,可以在降低信号处理瞬时带宽的条件下实现高距离分辨力,是一种很受关注的信号形式。文中分析了这种信号在均匀圆阵的宽角发射时波束方向的偏移情况,并提出了一种基于直接数字频率合成(DDS)的波束形成方法,仿真结果证明该方法是有效的。As a wideband signal,the stepped frequency signal is focused on for its high distance resolution in the renduction of instant processing bandwidth.The beam pointing errors in the presence of large scan angle is analysised and a new beamforming method based on the DDS is presenced.The simulation results indicate that the method is effective.
