受多波束特点及水体环境的影响,多波束边缘波束的数据质量低于中央波束的数据质量.通过分析多波束边缘波束测深误差的影响因素,提出了通过相邻条带中央波束的水深数据获取地形趋势面来提高边缘波束的水深数据质量.在此基础上,推导出了水底地形的曲线拟合公式和边缘波束测深点误差改正公式,并采用了多波束实测数据进行了验证.结果表明:使用该方法处理后的多波束边缘波束水深数据质量明显提高,水深数据更接近真实水深,有效削弱了多波束边缘波束的测深误差,对如何提高多波束的边缘波束数据质量有指导作用.研究成果可应用于多波束数据处理软件的深度研发和多波束实测数据后处理.
Research on edge beam data processing method of multi-beam based on terrain trend surface
Due to the influence of multi-beam characteristics and water environment,the data quality of multi-beam edge beam is lower than that of central beam.By analyzing the factors affecting the sounding error of multi-beam edge beam,it was proposed that the depth data quality of edge beam can be improved by obtaining the terrain trend surface from the depth data of adjacent band central beam.On this basis,a curve fitting formula and edge beam sounding point error correction formula were de-rived,and it was verified by multi-beam measured data.The results showed that the depth data quality of multi-beam edge beam was obviously improved by using this method,and the depth data was closer to the real depth,which effectively weakened the sounding error of multi-beam edge beam,and can guide to improve the data quality of multi-beam edge beam.The research results can be applied to the deep development of multi-beam data processing software and post-processing of multi-beam measured data.
