雷达系统分析与设计一书的部分matlab代码。《雷达系统分析与设计》是2008年由电子工业出版社编辑出版的马哈夫扎(MahafzaBassemR.美国)的电子通讯类专著。本书描述了雷达截面积、极化、匹配滤波器和雷达模糊函数及雷达波传播的最新进展，并给出了关于PRN码、多径和折射、高距离分辨率、杂波与MIT处理的有关内容。(Radar systems analysis and design of a part of the matlab code. Radar systems analysis and design in 2008 by the Electronic Press editor industrial publishing Mahafuzha (MahafzaBassemR. USA) electronic communications monographs. This book describes the radar cross section, polarization, and radar matched filter function fuzzy latest progress and radar transmission, and gives information about the PRN code, multipath and refraction, high range resolution, clutter and MIT-treated related content.)

自己做的一个ZC序列的生存文件，希望大家喜欢(ZCSquence)

The method works as follows. 1. For a data set with dimensionality, d, compute the variance of data in each dimension (column). 2. Find the column with maximum variance call it cvmax and sort it in any order. 3. Divide the data points of cvmax into K subsets, where K is the desired number of clusters. 4. Find the median of each subset. 5. Use the corresponding data points (vectors) for each median to initialize the cluster centers.
