中文说明：
线性调频脉冲压缩的Matlab程序，用于建立主成分分析模型，最终的权值矩阵就是滤波器的系数，包括脚本文件和函数文件形式，与理论分析结果相比，可以动态调节运行环境的参数，可以得到很精确的幅值、频率、相位估计。
English Description：
The matlab program of LFM pulse compression is used to establish the principal component analysis model. The final weight matrix is the coefficients of the filter, including script file and function file. Compared with the theoretical analysis results, it can dynamically adjust the parameters of the operating environment, and obtain very accurate amplitude, frequency and phase estimation.
