摘要: 为了解决现有水下航行器传感器布局优化中理论缺乏、传感器阵列分布简单和探测目标物运动形式单一等问题,基于贝叶斯概率模型的顺序启发式传感器优化布置方法,优化设计了探测两种不同运动类型目标物位置的传感器阵列,结合相对熵与顺序启发式算法构建目标函数,利用相关性系数设计评估函数,共同构建了仿生侧线传感器阵列优化理论模型。通过流场仿真构建了多种运动类型目标物的流场仿真数据库,使用不同运动类型目标物流场仿真数据概率表征不同阵列探测目标物位置的准确度。通过设计水下仿生侧线优化阵列探测试验系统,对所设计的优化阵列进行了探测准确性的优劣评估。仿真分析结果表明,相较于传统均匀阵列和经验阵列,所设计的优化阵列对水平和竖直振动偶极子目标物位置的探测概率分别平均提高了50.78%与 29.69%;优化阵列验证试验表明,相较于均匀阵列与经验阵列,所设计的优化阵列对水平和竖直振动偶极子目标物位置的探测概率分别平均提高了53.37%与9.80%,有效提高了对多运动类型目标物探测的准确度。

Abstract: In order to solve the problems of missing optimization theory, simple distribution of sensor array and single mode of detecting object motion in existing sensor array placement optimization of underwater vehicle, a sensor array for detecting the position of two different moving objects was optimized based on the sequential heuristic sensor layout method of Bayesian probability model. Combining the relative entropy and sequence heuristic algorithm to construct the objective function, and using the correlation coefficient to design the evaluation function, the theoretical model of artificial lateral line sensor array optimization is constructed. The flow field simulation database of various moving objects is constructed by flow field simulation. The probability of the flow field simulation data of different moving objects is used to characterize the accuracy of different arrays in detecting the location of objects. The detection accuracy of the optimized array is evaluated by designing the experimental system of underwater artificial lateral line optimization array. The simulation results show that compared with the traditional uniform array and the empirical array, the optimized array has an average detection probability of 50.78% and 29.69% higher for the position of the horizontal and vertical vibrating dipole target, respectively. The experimental results show that compared with uniform array and empirical array, the optimized array has an average detection probability of 53.37% and 9.80% higher for the position of the horizontal and vertical vibrating dipole target, respectively, which effectively improves the detection accuracy of multi-moving objects.

Key words: underwater vehicle, artificial lateral line, horizontal/vertical vibration target detection array optimization, bayesian probability model
