结合以往主动声呐信号仿真对于目标构建较为简单、仿真回波与真实回波拟合度较低且数值积分计算量庞大、不利于复杂目标的实时预报的缺点,在构建海洋环境噪声、海洋混响模型的基础上整合亮点模型进行了舰船主动声呐回波信号仿真。经水池实验验证,与实验回波数据相比达到了预期效果,为声呐设备的测试改良提供了良好的借鉴和思路。

Underwater target detection is one of the key technologies in navigation.The previous active sonar signal simulation has the shortcomings of relatively simple target model, low degree-of-fitting of the simulated echo with the real echo, and large computation burden, which is not suitable for real-time prediction of complex target.Based on building up the models of the ocean ambient noise and the ocean reverberation, we made active sonar echo signal simulation for the ship by using highlight model.The result of pool experiment showed that, the echo reached the expected effect in comparison with the echo in experiment, which supplied a reference for test improvement of the sonar set.
