| 摘 要： | 在多波束测深系统中,表层声速是线型接收换能器基阵对接收波束进行束控的重要参数。表层声速误差会直接造成接收波束的指向误差,也通过归算导致多波束脚印位置误差和回波图像的失真。在分析多波束信号处理流程和接收波束束控原理基础上,探讨表层声速对多波束指向和测深影响规律。

| Abstract: | For multibeam bathymetric system,surface sound velocity plays an important role in beam forming.The error in surface sound velocity will distort beam directions,which will lead to mistakes in final footprint calculation and echo beam image.Based on studying the processing flow of multibeam signals and the control principle of receiving the beam,this paper analyzes the influence of surface sound velocity in multibeam positioning and shows how to minimize the effects in the end. |

| Keywords: | multibeam echo sounding surface sound velocity meter wave beam angle |
