摘要
超短基线定位系统由于基阵尺寸小、安装方便,在海洋开发中得到了广泛的应用。高精度超短基线定位系统的安装误差影响不可忽视,需要在使用前进行精确校准,同时在深海使用条件下,声线修正是必需的。提出了一种基于最小二乘的结合声线修正的超短基线定位系统安装误差校准方法,该方法性能稳定、计算量小,湖上和海上试验验证了算法的有效性。
Uhra-Short Base Line system(USBL) is widely used in ocean exploitation because of its small aperture size and easy installation.The installation error in a highly precise USBL can not to be ignored before its actual application.The sound velocity correction is necessary.Based on Least Square(LS) principle,we propose in this paper a new algorithm on installation error calibration applied in USBL together with the sound velocity correction.This method provides the merits of stable performance and small computation.Lake and sea trial results confirm the validation of the proposed new algorithm.
