摘要
为了探测识别主动声呐发射的高频脉冲信号,设计了一种数据采集处理系统,可以对水听器接收到的声脉冲信号进行采集存储,并且能实时估计出声脉冲的幅度、宽度和频率等特征信息。该系统可以嵌入水下声对抗平台,用于探测识别携带侦察声呐工作的敌方目标。
In order to detect and identify the high-frequency pulse signal emitted by the active sonar,a data acquisition and processing system is designed,which can collect and store the acoustic pulse signal received by the hydrophone,and can estimate the amplitude,width and frequency of the acoustic pulse in real time.The system can be embedded in an underwater acoustic coun⁃termeasure platform for detecting and identifying enemy targets that carry reconnaissance sonar.
