| 为提升水下平台对目标的探测精度,设计并验证了一套布设于载体舷侧的声纳系统。系统由水听器阵列及电子系统组成,并工作在被动声纳模式。采用相移波束形成技术对接收信号进行空域处理以估计目标方位角,利用匹配滤波技术对回波信号进行处理以估计目标距离;电子系统部分采用低噪声信号调理及同步采集模块,实现对48通道声学信号的低噪声同步捕获,并设计了高速大容量存储系统保障数据的实时记录。实验结果表明，电子系统自噪声谱级低至2.52 nV/√Hz @40 kHz,系统整体幅度一致性误差小于3 dB,相位一致性误差低于6°。系统具备2.10°和1.35 m的分辨能力,以及3.96°和2.12%的定位误差。 |

| To enhance the detection accuracy of underwater platforms for targets, this paper designs and validates a sonar system mounted on the flank side. The system omprises a hytrophone array and an electronic subsystem, operating in passive sonar mode. System employs phase-shifted beamforming technology to process received signals in the spatial domain for target azimuth estimation, and utilizes matched filter technology to process echo signals for target range estimation. The electronic subsystem incorporates low-noise signal conditioning and synchronous acquisition modules to achieve low-noise synchronous capture of 48-channel acoustic signals, and features a high-speed, large-capacity storage system to ensure real-time data recording. Experimental results demonstrate that the electronic system self-noise spectral density is as low as 2.52 nV/√Hz @40 kHz, with inter-channel amplitude consistency error below 0.4 dB and phase consistency error under 2°. The system exhibits an overall amplitude consistency error of better than 3 dB and a phase consistency error of below 6°. It is capable of achieving a resolution of 2.10° and 1.35 meters, with a localization error of 3.96° and 2.12%. |
