“RADAR SIGNAL ANALYSIS AND PROCESSING USING MATLAB”。matlab对雷达信号的分析与处理（英文版），是学习处理雷达信号的入门教材。主要内容有雷达系统原理介绍和常用matlab函数。(" RADAR SIGNAL ANALYSIS AND PROCESSING USING MATLAB" . is a primary book of radar signal processing. The main contents is introduction of radar systems and some matlab functions.)

周期图法谱估计需要对信号序列“截断”或加窗处理，其结果是使估计功率谱密度为信号序列真实谱和窗谱的卷积，导致误差的产生。本程序分别设计了周期图法,最大熵功率谱估计和Welch法以及它们的对比,最大熵功率谱估计目的是最大限度地保留截断后丢失的“窗口”以外信号的信息，使估计谱的熵最大。(Periodogram spectrum estimation signal sequence needs to " cut off" or add the window handle, the result is an estimated power spectral density of the signal sequence of the real spectrum and spectral convolution window, resulting in the generation of errors. The procedures were designed periodogram, maximum entropy power spectrum estimation and the Welch method and their comparison, the maximum entropy power spectrum estimation purpose is to maximize the retention of truncated after the loss of the " window" than the information signal, the entropy of the estimated spectrum maximum.)
