摘要
FIR与IIR频率选择滤波器的设计,被广泛应用于数字信号处理领域之中。文章以雷达回波信号的数字处理为例,首先分别设计FIR,IIR滤波器完成了对信号特定频率分量的滤除。进而,针对IIR滤波器的非线性相位,基于最优化设计全通系统实现了相位补偿,并对FIR,IIR滤波器进行了综合比较。
The design of finite impulse response and infinite impulse response frequency selective filters are widely used in digital signal processing. Taking the digital processing of radar echo signal as an example, FIR and IIR filters are designed to eliminate the specific frequency components of radar signal, respectively. Furthermore, given the nonlinear phase of IIR filter, an all-pass system is designed to realize phase compensation based on optimization. Finally, FIR and IIR filters are compared accordingly.
