复杂地形水域单波束混响数据的处理研究

Processing Research of Complex Terrain Waters Single Beam Reverberation Data

摘要: 单波束HY1601在测量复杂的水下地形中，易发生声波混响效应，本文根据单波束测深原理及混响的模型，通过预估测量区域的水深深度来计算传播时间t，在测量软件中设置阈值，大于传播时间t后拒绝接受回声波，可消除声波的混响效应，获得正确的水下地形数据。

Abstract: Single beam HY1601 is prone to acoustic reverberation effect in measuring complex underwater terrain. According to the single beam sounding principle and reverberation model, this paper cal-culates the propagation time t by estimating the water depth of the measurement area, sets the threshold in the measurement software, and refuses to accept the return sound wave after it is greater than the propagation time t, which can eliminate the reverberation effect of sound wave and obtain correct underwater terrain data.
