电子战工具箱,不仅可以提高开发仿真程序的速度,对于初学者来说,也是理解电子战原理的素材(Electronic warfare toolbox can not only enhance the speed of development of simulation program for beginners, but also understand the principles of electronic warfare material)

详细画出了时域和频域的相关图，包括面积、周长、矩形度、伸长度，采用的是脉冲对消法。( Correlation diagram shown in detail the time domain and frequency domain, Including the area, perimeter, rectangular, elongation, It uses a pulse of consumer law.)

随着计算机技术的迅速发展和越来越广泛深入地应用于国民经济和社会生活的各个方面，随着 软件系统的规模和复杂性与日俱增，软件的生产成本和软件中存在的缺陷和故障造成的各类损失也 大大增加，甚至会带来灾难性的后果。软件质量问题已成为所有使用软件和开发软件的人关注的焦 点。由于软件是人脑的高度智力化的体现和产品这一特殊性，不同于其他科技和生产领域，因此软件与生俱来就有可能存在着缺陷。(With the rapid development of computer technology and the more extensively used in the national economy and social life in all its aspects, with the growing size and complexity of software systems, software production costs and software defects and faults caused various types of losses also increased significantly, even catastrophic consequences. Software quality has become the focus of all those who use the software and software development concern. Because the software is highly intellectual expression and product of the special nature of the human brain, unlike other areas of technology and production, so the software may be born with a defect exists.)

说明：  对心直动凸轮机构压力角的计算 计算斜齿轮公法线长度及其偏差 优化设计的分析与计算(Direct action on the heart cam pressure angle calculating the length of common normal helical gear calculation and deviation analysis and calculation of optimal design)

说明：  Cachy分布，产生cachy 分布的概率密度，随机数(Cachy distribution)

介绍MATLAB中灰度共生矩阵的文档，刚入门的可以拿去看看！(Documents introduced in MATLAB GLCM, just getting started can take it and see!)

实现了CA-CFAR算法仿真，得到其检测门限及检测概率曲线。并使用基于蒙特卡洛仿真方法得到检测门限及检测概率曲线，与传统的CA-CFAR算法进行了比较。(CA-CFAR algorithm to achieve the simulation, its detection threshold and detection probability curve. And use the resulting Based on Monte Carlo simulation method detection threshold and detection probability curve, with the traditional CA-CFAR algorithm were compared.)

说明：  有三种算法，分别是cmeans、fcm和som等对如iris和usps等数据的聚类。(There are three algorithms, cmeans, FCM and SOM to cluster data such as iris and USPS.)

通过ssr算法，在YCBCR空间上 对Y分量单独处理，来实现对图像光照不均匀处理，效果很好 可以继续改进(By ssr algorithm, YCBCR space on the Y component alone, to achieve uniform illumination of image processing, the effect is very good to continue to improve)
