本文通过matlab仿真，比较线性调频信号的FFT和STFT，并研究了信号中混入各种噪声后如何处理。(In this paper, matlab simulation, comparison of the FFT and linear FM signal STFT, and studied all kinds of noise signals mixed How to handle.)

剪切图片，有利于初学者，希望能够帮助有些人(cut picture)

自己编写的一个大批量不同类别数据录入程序，并且为防止因为数据量太大导致程序运行缓慢，将其改写成分批小规模数据。方便了大规模数据处理慢带来的各种不变。(I have written a large quantities of different types of data entry procedures, and because the amount of data in order to prevent too much causes the program to run slowly, be rewritten into small batches of data. Facilitate the large-scale data processing slow and the various unchanged.)
