窄带信号単快拍测向 通过平滑 提高信噪比 (Narrowband signals and single-snapshot direction finding Improve the signal to noise ratio by smoothing)

对给定的含噪脉冲信号进行相关检测。检测结果用1、0表示。要求从文本文件中读入数据，分析滤波前后的信号统计特征：包括均值、方差、自相关和功率谱。设计参考信号，进行相关处理和检测；画出原始数据的曲线以及相关结果的曲线(For a given pulse signal associated with noise detection. Test results with 1,0 said. Asked to read from a text file into the data, analyze the demographic characteristics of the signal after filtering include: mean, variance, autocorrelation and power spectrum. Design reference signal, the associated processing and testing draw the curve of the original data and the associated results of the curve)

数字图像修复算法的评价标准也是从两个方面进行评价的，一个是修 复算法的效率，一个是修复后图像质量。修复算法的效率主要就是看修复 图像所用的时间，可以用时间就行量化。而图像质量很难从量上唯一的进 行评价，目前图像修复质量还没有统一的评价标准，从实际应用出发，修 复后图像质量的好坏大多数是从以下两个方面就行评价，修复后图像给人 主观上的“满意度”和客观上图像的cnr、enl、epi、psnr、snr来评判。(The evaluation criteria of digital image restoration algorithms are also evaluated from two aspects, one is repair. One of the efficiency of complex algorithm is the image quality after restoration. The efficiency of the repair algorithm depends mainly on the repair. The time spent on the image can be quantified in terms of time. But image quality is difficult to improve quantitatively only. At present, there is no uniform evaluation criterion for image restoration quality. Starting from practical application, repair The quality of restored images is mostly evaluated from the following two aspects, and the restored images are given to people. Subjective "satisfaction" and objective image cnr, enl, epi, psnr, SNR to judge.)

通过图像像素点之间的相关性来判断该像素点为噪声点还是信号点，进而对其进行滤波。(first, we judge the image pixel that it is noise pixel or signal pixel by compute the correlations between them.then we remove the noise of the image.)
