【摘要】 应答器越来越多地应用于各种水下作业,而其绝对位置的校准是工作的前提。在深海下由于声速的不均匀性,声线会发生弯曲。海底应答器绝对位置的校准需要进行声线弯曲修正。给出了一种深海条件下含声线弯曲修正的海底应答器绝对位置精确校准的方法。深海试验结果验证了该算法的有效性以及进行声线修正的必要性。更多还原

【Abstract】 The transponder,whose calibration of the absolute position is the precondition for operation,is used more and more widely in underwater construction.In deep sea the sound ray bends because the sound velocity is not constant.The algorithm needs to be corrected for sound ray bending.This paper proposes an algorithm of precise calibration of the transponder moored on the seabed in deep sea with the correction of the sound ray bending.The results of deep sea trial show the feasibility of the algorithm and the necessity of correcting the sound ray bending.更多还原
