摘　　要：针对一体式主动声诱饵边收边发模式出现的声串漏现象,引入有效消除声串漏的滤波器。针对高/低声速壳体材料的电子舱,以带限白噪声为激励信号利用自适应算法仿真串漏传递函数并配置到滤波器中,改变自适应滤波器阶数,分析自适应算法对高/低声速材料电子舱串漏传递函数仿真效果,评估增大声隔离度的能力。仿真结果表明,由于发射接收距离较近且电子舱壳体存在导致接收总声场发生严重畸变,增加自适应滤波器阶数可有效提高转发诱骗信号质量,增大系统声隔离度。Aiming at the sound leakage phenomenon in the integrated active sound decoy mode,a filter that effectively eliminates the sound leakage is introduced.For the electronic cabin of high/low sound velocity shell materials,the band-limited white noise is used as the excitation signal to use the adaptive algorithm to simulate the cross-leakage transfer function and configure it in the filter,change the order of the adaptive filter,and analyze the effect of the adaptive algorithm on Simulation effect of cross-leakage transfer function of electronic cabin of high/low sound velocity materials to evaluate the ability to increase sound isolation.The simulation results show that the total receiving sound field is severely distorted due to the short transmitting and receiving distance and the existence of the electronic cabin shell.Increasing the order of the adaptive filter can effectively improve the quality of forwarding decoy signals and increase the sound isolation of the system.
