spectrum of BPSK change with different probabilities

多个脉冲积累后可以有效地提高信噪比，中频积累时要求信号间有严格的相位关系，即信号时相参的，所以称为相参积累。(Multiple pulse accumulation can effectively improve SNR, if integration requires strict phase relationship between signals, whereby the signal coherent, so called coherent accumulation.)

FFT的频谱分析及应用 包括模拟信号 、连续信号、 以及噪声信号的频谱分析(FFT spectrum analysis and application of analog signals of a continuous signal and the noise signal spectrum analysis)

四种天线阵列加权分布。泰勒分布、二项式分布、傅里叶分布、切比雪夫分布。(Four kinds of antenna array weighted distribution.Taylor distribution, binomial, Fourier, chebyshev distribution.)

四旋翼无人机飞行仿真程序，用于四旋翼无人机的模拟飞行。(Four-rotor UAV flight simulation program for the four-rotor UAV Flight Simulator.)

图像噪声消除,采用小波分析的方法，阈值法进行系数矫正(figure noise )

说明：  毫米波图像超分辨复原，采用基于最大似然函数的算法，实现频谱外推(Millimeter wave image super-resolution restoration, using an algorithm based on maximum likelihood function, the spectrum extrapolation)

说明：  通过比较自编MATLAB 的k-means 算法程序和SPSS 中自带的k-means聚类工具，对两个数据集聚类，并分析了聚类结果。(By comparing the k-means algorithm program of self-compiled MATLAB with the K-means clustering tool of SPSS, two data sets are clustered and the clustering results are analyzed.)

插值与拟合,里面包含很多小程序，而已直接运行(Interpolation and fitting, which contains many small programs, it runs directly)

多元统计方法是处理高维、相关数据的有效工具，其首先 在化工过程的故障检测中得到成功应用，后也被应用于其他的 工业过程(Multivariate statistical methods to deal with high dimension and effective tool for data, the first fault detection in chemical process has been successfully applied, the latter also used in other industrial processes)
