为了弥补声相关计程仪(ACL)工作原理只能利用几何关系描述的不足,以声呐方程为基础,采用Kirch-hoff近似模型,研究了基于混响网络模型的海底回波.利用仿真回波数据及时-空相关函数,推导出船速从一维到三维不同条件下,采用平面阵进行接收时,满足两接收阵元接收回波相关性最大的条件,从而给出了波形不变性原理的一种数学描述方法.仿真结果证明了该描述方法的有效性.
In order to make up for the working principle of Acoustic Correlation Log (ACL) algorithm, we can only make use of the description of the geometric relationship, and based on the sonar equation, the Kirch-hoff approximation model is used to study the submarine echo based on the reverberation network model. Data and time-space correlation function, we derive the condition that the receiving eigenvalues of the two receiving elements receive the maximum correlation when the ship speed is received by the plane array under one-dimensional to three-dimensional different conditions, and thus one Mathematical Description Method The simulation results show the effectiveness of this method.
