《水和水蒸气性质表》，用matlab编的源程序，希望大家喜欢(" Water and Steam Properties Form" , using matlab source code, hope you like)

描述了13阶巴克码信号的特性，画出了图形，并做了脉冲压缩处理，比较了用一般旁瓣抑制滤波器与等副瓣法设计旁瓣抑制滤波器进行旁瓣抑制的差别，给出了图示。(Describe the 13 order Barker code signal characteristics, draw the graphics, and the pulse compression processing, compared with the general sidelobe suppression filter with side flap design of sidelobe suppression filter for sidelobe suppression of difference, gives some graphic.)

this is good code.for our learing.

利用matlab提供的引擎接口函数与VC联合开发编程，可在VC中充分发挥matlab强大的数值运算功能，弥补VC中数值运算函数的不足(err)

根据D.C.CHU提出的计算CAZAC序列的算法，计算出CHU序列的matlab程序。包括自相关函数，FFT变换后的CHU序列，以及CAZAC序列的一些特性，还提供D.C.CHU的算法原文(According to the calculation made by CAZAC sequence DCCHU algorithm to calculate the CHU sequence matlab program. Including the self-correlation function, FFT transformed CHU sequence, as well as some of the characteristics CAZAC sequence)
