The method utilizes an AR model to approach the frequency response of the clutter spectrum "inverted" ideal band-pass filter, and then implements the design of optimal FIR filter.
该方法利用AR模型逼近杂波谱“倒置”理想带通滤波器的频率响应，实现了最优FIR滤波器的设计。

The purpose of optimizing phase response characteristic is to obtain flat group delay characteristic at Passband.
而对相频特性优化的目的是要在通带内获得平坦的群时延特性。
