基于Simulink的鱼雷尺度靶收发干扰仿真

The Torpedo-scale Target Transceiver Interference Simulation Based on Simulink

在分析尺度靶多亮点目标模型的基础上,建立了拖曳线列阵靶收发干扰和信号处理模型,然后利用Simulink工具箱对干扰模型进行了仿真,最后给出了仿真结果。结果表明,靶标收发换能器间的干扰会导致转发信号产生畸变,但其畸变对信号幅度的影响较小,不会对目标模拟产生影响,验证了拖曳靶进行目标模拟的可行性,对鱼雷尺度靶及其它水声目标模拟设备的研制有一定的参考应用价值。

The paper establishes target towed cable-array transceiver interference and signal processing model based on the analysis of multi-highlights model of the target scale, and then simulated the interference simulation model using simulink toolbox and conclude the results finally. The results show that the interference between the target transceiver transducer can causes the transmitted signals distorting, but the impact of distortion on the signal amplitude is small and won＇t have an im- pact on the target simulation. It verified the feasibility of the target simulation based on towed cable-array, and also have some reference value for the developing of torpedo-scale targets and other underwater acoustic targets simulation equipment.
