摘要
推导了多波束测深脚印位置归算模型,通过与CARIS软件进行实例比对,验证了该模型的有效性。在数据处理过程中,采用时标序列检索的方式处理导航时间延迟,取得了良好的效果;采用条带姿态进行姿态改正避免了"杠杆"旋转对边缘波束深度的影响。实例比对表明,该模型结果与CARIS软件输出结果一致。
A new multibeam echosounding depth determination model is deduced on the basis of data format analyzing.Comparing with CARIS6.1,the model is proved effective.In data processing,using time tag to deal with navigation latency achieves higher precision,and swath attitude is also accepted to avoid level rotation which inflects outer beam depth.A data processing example shows that the model plays as well as CARIS.
