| 中文摘要: |
| 在水声信号处理中,有时普通滤波器不能够满足应用要求,需要利用具有任意的给定频率响应的滤波器。本文利用自适应方法设计具有给定频率响应的FIR滤波器,并将该方法设计的滤波器用于产生宽带信号的精确时延信号和进行时域宽带波束形成,使用效果较好。该类滤波器使用非常有效,而且计算量小,易于工程实现。 |

| A method to design a finite impulse response (FIR) filter with specific frequency response is presented. Specific frequency response FIR filter can be designed to well satisfy given requirement by use of adaptive method. This kind of filter can find important applications in underwater acoustic signal processing. Precise time-delay filter and time-domain broadband beamformer well suited for sonar application are herein illustrated. The FIR filter needs less computation and can easily be carried out by commonly available DSP chips. |
