雷达经典的书，基础知识讲的很清楚，当时上课的时候用的书(Radar classic book, the basics of speaking very clearly, the class was a book )

两个数值实验的matlab编程实现。题目分别1是利用循环语句，计算数列根号5 ，根号下根号5 ，根号下根号下根号5…的极限，要求误差小于 10负8次方。 2利用级数pi=1-1/3+1/5-1/7+...可计算出无理数pi的近似值(Two numerical experiments matlab programming. Title 1 is the use of loop were calculated series roots and 5, roots and root number under 5, roots and root, root number under number 5 ... the limits of error of less than 10 required a negative 8th power. 2 using series pi = 1-1/3+1/5-1/7+ ... calculate the approximate irrational number pi)

是信号处理的基础，是路径规划的实用方法，本程序的性能已经超过其他算法，基于负熵最大的独立分量分析，包括调制，解调，信噪比计算，毕业设计有用。

平均周期法计算 fft的结果，Bartlett平均周期图的方法是将N点的有限长序列x(n)分段求周期图再平均，Welch法对Bartlett法进行了两方面的修正，一是选择适当的窗函数w(n)，并再周期图计算前直接加进去，加窗的优点是无论什么样的窗函数均可使谱估计非负。二是在分段时，可使各段之间有重叠，这样会使方差减小。 -The average cycle method to calculate the fft results, Bartlett average periodogram method is limited to N-point long sequence x (n) Sub-seeking re-average periodogram, Welch method of Bartlett law was amended in two areas, first select the appropriate The window function w (n), and re-cycle before CALPHAD directly incorporated, plus the advantage of a window no matter what kind of window function will be to make spectrum estimation of non-negative. Second, in sub-paragraph, the can have overlap between the paragraphs, it may lead to variance reduction.
