对二维矩形阵列，进行空间谱估计！适合阵列测向的新手，建议先仔细学习基础知识。在知识积累上想进行垮越式发展，于初学者来说最重要的是能帮助你弄清楚问题根本何在。 (Of two-dimensional rectangular array, spatial spectrum estimation! Suitable for the novice to the array of measurement, it is recommended to carefully study the basic knowledge. In the accumulation of knowledge on Vietnam-style collapse would like to carry out development for the beginner to the most important thing is to help you figure out what the problem is.)

说明：  对信号进行短时傅里叶变换和小波变换，观察其时频特性，压缩包中含有需要用到的测试信号文件，可以直接运行，供参考(Carry out short-time Fourier transform and wavelet transform on the signal, observe its time-frequency characteristics, and the compression package contains the test signal files needed, which can be directly operated for reference)

随机共振的很多例子的集合体。matlab代码可以作为参考。(Stochastic resonance in a collection of many examples. matlab code as a reference.)

说明：  利用最小二乘原理建立了趋势项的一般模型，并利用MATLAB软件强大的矩阵计算功能，对一个含有非线性趋势项的周期信号进行了趋势项消除，并得到了预期效果。(Using the least squares principle to establish a trend term, the general model and the use of MATLAB software is powerful matrix calculation function, for a linear trend term with periodic signals the trend for elimination, and get the desired effect. )
