设计最小二乘逆滤波器求解反卷积问题,假设有观测噪声,为降低观测噪声的影响，可采用预白化方法,设计长度N=50的最小平方FIR逆滤波器(inverse filter design for least squares deconvolution, the assumption that the measurement noise, To reduce the impact of noise and possible pre-whitening method, the length N = 50 the minimum inverse square FIR filter)

MUSIC算法[1]是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成，噪声子空间则由协方差矩阵中所有最小特征值（噪声方差）对应的特征向量组成。(MUSIC algorithm [1] is a feature space based on matrix decomposition method. From the geometric point of view, the signal processing can be decomposed observation space the signal subspace and the noise subspace, it is clear that the two spaces are orthogonal. Signal Subspace data received by the array covariance matrix and eigenvectors corresponding to the signal component, the noise subspace from the covariance matrix of all the smallest eigenvalue (noise variance) eigenvector components.)

批处理选择年代不同的数据 如1951年开始到2010年的数据，统一选择为1971-2010年，该程序可以实现(Batch select from different data such as the 1951 to 2010 data, unified Select year 1971-2010, the program can be achieved)
