一种带有时变偏执项的比例导引制导律，学习研究落角约束方面的经典文章，鼻祖级别！(Proportional navigation guidance law one with varying paranoid items, study the impact angle constraint classic article, the originator of the level!)

使用matlab对给定的图像进行提取rgb颜色特征，并输出颜色直方图(use matlab to extract the rgb feature )

MATLAB代码实现PID自适应控制(MATLAB and PID control)

说明：  用MATLAB实现频域平滑滤波以及图像去噪代码6. 计算频率域图像的幅值并进行对数变换，利用’imshow’ 显示频率域图 像； 7. 在频率图像上去除滤波半径以外的数据(置0)； 8. 计算频率域图像的幅值并进行对数变换，利用’imshow’ 显示处理过的 频域图像数据； (6. Calculate the frequency domain image of the amplitude and logarithmic transformation, using imshow show the frequency domain map Like 7. Removal of the image filtering in frequency than the radius of data (set 0) 8. Calculate the frequency domain image of the amplitude and logarithmic transformation, using imshow show-treated Frequency domain image data )

Surfer是地学中常用的一个软件，可以完成等值线图，立体图，流向图等的汇制。其自带的类VBA的开发语言，可以进行二次开发。附件是一些源程序。其中的Jackknifes可以用来对比不同的内差方法，从而得出最优化的内差方法。 (Surfer is the study of a commonly used software, complete contour map, a three-dimensional map, map the flow of the system. Its built-in categories VBA programming languages that can be re-developed. Annex some source. Jackknifes which can be used for comparison within the poor, so as to come up with the most optimal way worse.)

等间距线性阵列，阵元数M=8，阵元间距d= λ /2，目标方位φr =0°，无噪 分别仿真计算等幅加权、汉宁窗加权、切比雪夫加权时的阵列方向图，定性分析产生的原因。（可分析不同窗函数引起的主瓣、旁瓣影响） (Equally spaced linear array, the number of array elements M = element spacing d = λ/2, target azimuth φr = 0, no noise respectively simulation amplitude weighted Hanning window weighted cut than snow laid upon the right of the array direction diagram, the qualitative analysis of the causes. (May analyze different window function causes the main lobe, side lobe effects))

FSK的SIMULINK仿真代码，包括调制解调与频分复用(FSK simulink modulation and demodulation)

说明：  二维冲突概率算法，其实这个仿真是为了验证三维算法实现的基础，在二维的基础上再把二维扩展到三维。但也有不一样的地方(Two-dimensional conflict probability algorithm, in fact, this simulation is to verify the basis of three-dimensional algorithm, based on the two-dimensional two-dimensional and then extended to three-dimensional. But there are also not the same place)

对于具体实验时，通常不是先给出函数的解析式，再进行实验，而是通过实验的观察和测量给出离散的一些点，再来求出具体的函数解析式。又因为测量误差的存在，实际真实的解析式曲线并不一定通过测量给出的所有点。最小二乘法是求解这一问题的很好的方法，本实验运用这一方法实现对给定数据的拟合。(For specific experiments, usually not first given function analytic formula, and then experiment but given by the experimental observation and measurement of a number of discrete points, and come back to find the specific function analytic formula. And because the presence of measurement error, the actual real analytic curve does not necessarily pass through all points of measurement given. The least squares method is a good way of solving this problem, the experimental use of this method of fitting the given data.)
