| 中文摘要: |
| 在从信号处理的角度,就干扰信号对被动声呐系统的目标信号检测、目标方位估计、接收系统饱和等方面的典型情况进行了仿真分析,定义了噪声掩盖比、方位偏离度、噪声阻塞级等参数,用以表征干扰信号对被动声呐系统的影响,并给出了典型的仿真结果。 |
| 英文摘要: |
| In the paper, several typical effects of noise interference on passive sonar system are analyzed via signal processing method, which concern the key procedures of underwater passive sonar system, such as signal detection, DOA (Direction Of Arrival) estimation and system saturation. Three indices are introduced to evaluate the noise interference effects including the power ratio of signal to jammer, the error of estimated DOA and the block interference power. Simulation results that demonstrate the effect are given. |
