摘要

摘要: 针对水下小目标采取规避动作形成跟踪丢失, 不易探查, 进而导致安防系统虚警率较高的问题, 文中在固定式声呐检测到目标并不断获取相关数据的前提下, 考虑搭载图像声呐的无人艇对目标进行近距离查证的情景。通过固定式声呐获取目标的轨迹数据, 而后采用粒子滤波方法对轨迹数据进行预测。随后建立我方无人艇与敌方目标的博弈模型, 根据敌方目标每一时刻的动作和模型中的支付函数, 选择对我方最有利的决策, 以此形成双方的对抗过程。最后通过数值仿真得到无人艇的目标点和探查策略, 并利用试验数据验证目标点的准确性, 方便无人艇成功探查目标。文中研究可为无人系统探查小目标提供理论依据。

Abstract: Owing to the evasive action of small underwater targets, they are lost and difficult to detect, which leads to a high false alarm rate of the security system. Based on stationary sonar detection of the target and continuously obtaining relevant data, this study considers the scene of an unmanned surface vehicle (USV) that carries the image sonar to verify the target at a short distance. First, the trajectory data of the target are obtained using stationary sonar, and then the particle filter method is used to predict the trajectory data. Then, a game theory model between our USV and the enemy target is established. According to the action of the enemy target at every moment and the payment function in the model, our USV chooses the most favorable decision to form the confrontation process of both sides. Finally, the target points and detection strategies of the USV are obtained through a numerical simulation. The accuracy of the target point was verified by the test data, which is convenient for the USV to successfully detect the target. The results of this study provide a theoretical basis for unmanned systems to detect small targets.
