说明：  不变矩是模式识别里面很重要的一种技术，它可以用于提取不变性特征，从而进行模式识别，广泛用于图像处理当中，如图像特征匹配(Moment invariant pattern recognition which is a very important technology that can be used to extract invariant features for pattern recognition which is widely used in image processing, such as an image feature matching)

水下信号与信息处理中，为了准确估计方位，把波束分为左右两路波束，成为虚拟阵元，然后计算方位。(Underwater signal and information processing, in order to accurately estimate the orientation of the beam into two beams around and become virtual array, and then calculate the position.)
