FIR(Finite Impulse Response)滤波器：有限长单位冲激响应滤波器，是数字信号处理系统中最基本的元件，它可以在保证任意幅频特性的同时具有严格的线性相频特性，同时其单位抽样响应是有限长的，因而滤波器是稳定的系统。因此，FIR滤波器在通信、图像处理、模式识别等领域都有着广泛的应用。 (FIR (Finite Impulse Response) filters: finite impulse response filter unit, digital signal processing system is the most basic components, it can ensure that any increase in the frequency characteristics of both a strictly linear phase frequency characteristics, while its unit sample response is finite, and therefore the system filter is stable. Therefore, FIR filters in communications, image processing, pattern recognition and other fields have a wide range of applications.)

雷达信号目标跟踪的相关程序，可以借鉴一下！很有用的！(Image processing procedures, can learn about! Very useful!)

给定一个普通多项式p(x)，用列向量表示，阶次从高到低排列，此函数返回p(x)的切比雪夫多项式展开的系数，返回的的结果也是一个列向量，同样按切比雪夫多项式的阶次从高到低排列(Given a general polynomial p (x), with a column vector representation, the order highest to lowest, the function returns p (x) Chebyshev polynomial expansion coefficients of the returned result is a column vector, the same press cut the order highest to lowest Chebyshev polynomials)

一、观察序列频谱，观察信号通过系统后波形与频谱的变化。 系统函数，根据正准型结构（canonical form）编写样本处理算法。 (First, observe the sequence of the spectrum, observing the signal waveform and frequency spectrum through the system after the changes. System function, according to canonical structure (canonical form) the preparation of a sample processing algorithm.)
