说明：  语言的宏定义指令集，本文章还不错，希望大家多看看，给出宝贵意见。(Macro definition language instruction set, the article was not bad, I hope to see everyone and more is given valuable advice.)

互相关模糊函数的matlab程序，很不错的，( cross_ambfn2.m- amodification of "ambfn1.m" for plotting cross ambiguity between two signals OF THE SAME LENGTH Designed to allow mismatch caused by FFT Doppler processing a pulse train. The two signals differ only in phases (if there is frequency mode it is the same in both signals. ambfn1.m- plots ambiguity function of a signal u_basic (row vector) The m-file returns a plot of quadrants 1 and 2 of the ambiguity function of a signal The ambiguity function is defined as: )
