By analyzing and processing the underwater sound signals received on the array , we can get the parameters of ocean environment . compared with traditional methods of direct point measurement , ocean acoustic tomography has obvious advantages : much simpler and more effective , and it can continuously monitor ocean environment in a large area for a long time 海洋声层析技术通过分析处理水声接收基阵接收到的海洋信道中的水声信号来反演海洋环境参数,这种方法方便、高效并且可以进行长时间的大范围连续监测,与传统的直接测量的方法相比有明显的优势。
