摘要
结合工程实例介绍了多波束测深数据后处理的操作流程,以及利用噪声变化限制范围和水深变化限制范围两种方法消除噪声导致的异常数据。针对多波束测量数据量庞大而影响后处理效率的问题,简要介绍了对测深数据进行抽稀简化的规则、方法。
Post processing operational process of multi-beam sounding system is introduced as well as two ways to eliminate the abnormal data caused by noise. In response to the problem of large multi-beam measuring data affecting the post-processing efficiency, we simply introduce some rules and methods to simplify the sounding data.
