摘　　要：利用摆动式单波束探测水下微地形时,因掠射角、底质特性等因素对回波信号的影响,导致数字高程粗差产生。本文根据摆动式单波束的探测原理和工作特点,对多波束测量中的数据加窗法进行改进:将回波能量作为探测点的内在属性参与确定起始加窗点;加窗点采用实测点,并要求起始加窗点尽可能靠近整条测线上实测点的高程均值。由此提高了高程粗差剔除的准确性。在实际应用中,随机微地形的高程粗差被成功剔除。Compared with cluster system, geospatial information grid computing mode takes on unparalleled advantages, because it can solve the problem of resource heterogeneity, supporting resource flexible retractility, many kinds of parallel programme environments, scientific computing database and tool-softwares, and video dynamic interaction between man and computer. The architecture of geospatial information grid computing mode is a kind of hierarchical structure with some intellectual capacity. Referring to the idea of Five-Level Sandglass Architecture and predecessor＇s productions, the author discussed and designed Multi-level Architecture of Geospatial Information Grid Computing System with six levels including resource base, security dispatch, abstract interface, middleware, applied interface and application.
