摘要
窄带阵列信号处理算法不能识别真实舰船和声模拟器,基于某水下武器的作用距离和舰船尺度是可比拟的分析。在对单矢量水听器输出信号阵列建模的基础上,建立了频率分段宽带MUSIC算法,应用于舰船目标信号波达方位估计,来对舰船体积目标进行识别。仿真和实测数据计算结果验证了其可行性。
The narrow band array signal algorithm can’t be used to identify the real ships or acoustic simulators. The analysis demonstrates that the striking distance of the underwater weapon and the scale of ship is near. A wide-band subsection-frequency MUSIC algorithm is established on the basis of single vector hydrophone array output signal model. The proposed algorithm is used for ship target recognition by target DOA. The simulation and measured results verify its feasibility.
