声尾流自导系统接收信号模型研究

Research on Receiving Signal Model for Acoustic Wake Homing System

研究了利用尾流回波信号、海面混响和航行噪声的声学模型生成作用于反舰自导接收通道时域信号的方法,并用上述声学模型,以国外对驱逐舰尾流气泡浓度测量数据和选取的自导参数为依据进行了定量计算,得到的波形与实航记录的波形相比具有一致性。研究结果可为电子注入式声尾流自导半实物仿真系统的信号生成提供依据。

The scatter models of wake and surface reverberation and the model of self noise are given in this paper. The generating methods of digital time series which received by the receiver of wake homing system are presented. Based on the above models, a digital simulation example of wake homing system is given, and the simulation results are in good agreement with sea trial ones. The methods can be applied to the wake homing hardware-in-the-loop simulation system.
