摘要
研究了吊放声纳模拟器主动探测建模与仿真技术。吊放声呐主动探测的效果除了受系统自身影响外,声速梯度、海况等水文条件对其也有很大的影响。在探测过程中,首先进行了波束判断,然后进行探测距离判断,提出一种基于恒定负声速梯度的声传播损失的计算模型,最后以声纳方程为基础,建立了主动探测的判断模型,并给出仿真结果。
Modeling and simulation of active detection of dipping sonar simulator are studied in the paper. The effect of dipping sonar active detection is affected not only by system factors, but also greatly affected by hydrographic conditions such as sound velocity gradient, sea conditions. Firstly, wave bunch is judged in the detection progress. Then detection range is judged, and the model for computing the acoustical transmission loss is proposed which is based on invariable minus gradient of sound velocity. Finally, a judging model of active detection is established based on sonar equation, and the result of simulation is also given.
