基于消声水池的多波束测深不确定度检测方法
|
Abstract:
目前国内多波束测深系统质量检验不够成熟，仪器质量和测量数据的可靠性和准确性都无法得到保证，为此，提出一种基于消声水池的多波束测深不确定度检测方法。通过建立基于消声水池的测深声呐检测硬件、软件平台，削弱了由于实验环境带来的各种误差及不确定度因素的影响，提高了检测的精度与可信度。对R2 Sonic2024型多波束测深仪进行几何指标检定实验和精度评定分析，精度较高的中央波束水深值总误差服从正态分布，计算其置信区间及落入置信区间的概率，剔除不符值，使其满足置信度为95%，并计算比对差均值。实验结果表明，该多波束测深不确定度检测方法切实可行，能比较客观地用于多波束测深不确定度检测
