利用matlab分析地震波场速度特征,是进行速度建模的基础(Matlab analysis of the use of the speed of seismic wavefield characteristics, speed of modeling is the basis of)

模拟2个独立窄带信号分别以20°，60°的方向入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵元间距为入射信号波长的1／2，快拍数为200，信噪比为20dB，阵元数分别为10，50，100。 (Simulate two independent narrowband signals in the direction of 20 °, 60 ° of the incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the array element spacing of the incident signal wavelength of 1/2, the number of snapshots 200, SNR is 20dB, the array element number 50, 100, respectively.)

选择13级移位寄存器的初始数据，用移位加反馈的方法生成级数为3~13的m序列(The selection of the initial data of 13 level shift register, series is generated by shift plus feedback method for 3 ~ 13 m sequence )

三维空间离散点的曲面拟合,以及散点图做法(Three-dimensional surface fitting discrete points, and scatter plots practice)

帧差发源代码，来自matlab中文论坛，毕业设计需要(The frame difference originated code from Matlab Chinese Forum, graduation design needs)

调用动态规划程序dynprog.m解决生产问题的举例及计算结果(Called dynamic planning process dynprog.m solve production problems and computations example)

该程序仿真了机载雷达对地面微动目标成像过程及结果。验证了微动的成对回波理论及微动对雷达成像造成的影响，改变微动参数，可看到鬼影点、灰度条带、直线圆列等由于微动参数不同而产生的不同现象。(refer to the chinese introduction)

说明：  K-均值聚类，比较好的聚类方法，应用广泛(K-means clustering, a better clustering method, widely used)

对时频峰值地震噪声的滤波及对实际信号的处理、(Time-frequency seismic noise on the peak of the actual signal filtering and processing,)
