说明：  该程序实现的是用标准卡尔曼和扩展卡尔曼滤波算法，对空中观测目标进行跟踪(The program is to use standard kalman and extended kalman filtering algorithm to track the air observation target)

说明：  用于替换某个文件,可无视任何权限,达到各种想要的功能(Used to replace a file, regardless of any permissions, to achieve the desired functions)

用以备份恢复的控件,支持压缩和分盘备份,可以部分恢复backfile(Delphi)()

说明：  主要的功能是鉴相 可以通过鉴相推算频率 简单的实现其主要功能 验证算法的正确性(The main function is that phase discrimination can simply realize its main function to verify the correctness of the algorithm by calculating the frequency of phase discrimination.)

C51的一些误区和注意事项（ZT） 1)C忌讳绝对定位。 常看见初学者要求使用_at_,这是一种谬误，把C当作ASM看待了。在C中变量 的定位是编译器的事情，初学者只要定义变量和变量的作 用域，编译器就把一个固定地址给这个 变量。怎么取得这个变量的地址？要用指针。比如unsigned char data x 后，x的地址就是... -C51 some errors and attention to the business (ZT) 1) C taboo absolute positioning. See beginners often require the use of _at_, this is a fallacy, ASM C as a treat. C variables in the positioning of the compiler things, as long as the definition of beginners variable and the variable scope, Compiler put a fixed address to this variable. How the variables made the address? Use indicators. Unsigned char data such as x, x is the address ...
