说明：  AVO 及其作用 AVO(Amplitude Versus Offset,振幅随偏移距的变化)技术用于研究地震反射振幅随炮点与接收器之间的距离即炮检距(或入射角)的变化特征(Amplitude Versus Offset)

基于matlab环境，利用舍选法，逆函数法生成随机数(Based on matlab environment, using rejection method, the inverse function method for generating random numbers)

这是一个kernel lpp流行学习算法（Kernel Locality Preserving Projections），(Kernel Locality Preserving Projections for manifold usingmatlab)

说明：  对于非均匀线型阵列，以降低波束方向图峰值旁瓣为目标，在给定阵元数和阵列孔径的约束条件下，利用多种群并行进化遗传算法进行阵元布阵优化。(For non-uniform linear array, in order to reduce the peak side lobe of beam pattern, the multi population parallel evolutionary genetic algorithm is used to optimize the array element arrangement under the constraint of the number of array elements and array aperture.)

这是在matlab下实现的包络检波算法。先对信号进行调制，然后进行包络检波。(This is achieved under matlab envelope detection algorithm. First signal modulation, and then proceed to the envelope detector.)
