针对结构转角信息难以测量的问题，采用转角信息重构技术由随机子空间从振动信号中提取的结构平动位移估算结构转动位移，然后构建改进的单元损伤变量(Since it is difficult to measure the rotational responses of a structure, a technique was adopted to evaluate the approximate modal rotations with the modal displacements, which were extracted from structural vibrational signals with stochastic subspace identification, by static condensation and QR decomposition)

使用M语言编程的PLL程序，可以快速的实现对相位的锁定。(PLL using the M programming language program, you can quickly lock the phase of realization.)

该程序用于生成一个线性调频信号（即chirp 信号），并对该信号进行压缩，显示结果图(to generate one chirp signal and then compress)
