信号与系统试验报告
离散傅立叶变换（DFT）和频谱分析
一、实验内容
1、实验题目
（1）编写DFT、IDFT程序，并验证其正确性（提示：可利用冲激函数进行验证）。
（2）计算信号f(t)=e-at2sin(2∏ft)的离散傅立叶变换（DFT），求其振幅谱，相位谱、振幅最大值对应的频谱（检测主频）以及对发f(t)进行DFT变换的结果实现IDFT变换，并画出图形。
参数选择如下：频率f =30HZ，a=f 2㏑(M),M=2.5
2、通过实验理解信号振幅谱、相位谱的物理意义，掌握DFT、IDFT算法的实现方法。()

关键(Scale adaptive mechanism in the target tracking algorithm based on Mean-Shift algorithm is an important direction of research. A typical method using Lindeberg' s scale space theory to obtain the target scale. However, the existing algorithms will scale from 2. D vector compression for 1-D volume, not fine to portray the target affine transformation of scale changes, thus limiting the scope of application of the algorithm. To this end, the paper will scale dimension. D filter to the 2-D structure has been the vertical D scale space and the use of narrow inter-dimension and scale dimension of the Mean-Shift alternating iteration, effective tracking of the target position in space and scale direction to improve the self-adaptive algorithm when the target scale changes, and to expand the scope of application of the algorithm.
