模拟两个相干的的窄带信号。阵列的阵元数为10,快拍数为200,信号入射方向分别为20°,60°,阵元间距为入射信号波长的1/2,信噪比为20dB。分别用MUSIC算法和改进MUSIC算法进行仿真。仿真结果如下图所示(MUSIC algorithm is improved compared with the simulation of signal coherent MUSIC algorithm. Two coherent analog narrowband signal. Array element number of the array 10, the number of snapshots 200, a signal incident directions, respectively 20 °, 60 °, array element spacing is 1/2 of the wavelength of the incident signal, SNR is 20dB. Respectively MUSIC MUSIC algorithm and improved algorithm simulation.)

Extract-wavelet
根据地震记录的统计特征和相应假设,本文采用
ARMA
模型描述地震子波,基于
高阶累积量的
ARMA
模型地震子波提取方法不仅可在压制高斯色噪声的同时保留所需
地震信号的相位信息(For the cumulant based ARMA (autoregressive moving average ) model seismic wavelet
extraction method could not only retain the pahse information of the seismic wavlet while
eliminating the colored Gaussian noise, but also provide a parsimonious, more efficient
)
