代码说明:

matlab计算分数阶傅立叶变换。对LFM信号进行加噪处理,通过frft+滤波器然后反frft得到去噪的信号。例程完整,有运行结果。lfm在声呐,雷达方面有巨大的应用。而frft是分数阶的傅立叶变换,通过做p阶变换得到了相应的参数,对lfm参数估计也有很好的作用。

    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.)
