| 摘 要： | 讨论了利用声相关流速剖面仪进行深水散射层观测的可行性。结合声相关流速剖面仪垂直发射编码调制信号、多阵元接收的特点以及测量流剖面三维速度的优势,提出利用回波强度和垂向速度两种方法对深水散射层进行观测。在23kHz声相关流速剖面仪工程样机海试数据的基础上,利用这两种观测方法对DSL进行了观测。观测结果表明：利用声相关流速剖面仪可以直观地观测深水散射层的分布及运动规律,这两种观测方法是实际可行的。

| Abstract: | The feasibility of observing deep scattering layer(DSL) by acoustic correlation current profiler(ACCP) is discussed in this paper.ACCP can estimate the three-dimension velocities of the currents.The projector of ACCP transmits code-modulated pulse vertically and several hydrophones receive backscattering signal.Two methods are presented to observe DSL respectively based on backscattering strength and vertical velocity.These two methods are used to observe DSL with the sea trial data of 23 kHz prototype ACCP.The results of the observation indicate that ACCP can observe the distribution and migration of DSL intuitively. |
