摘要:

在复杂水声条件下, 针对采用典型运动样式的水下目标的被动检测难题, 研究了一种自适应随机Hough变换检测前跟踪方法对水下旋回运动目标进行检测。首先, 根据水下目标旋回运动特点, 推导了小舵角旋回运动方程。其次, 通过构建自适应关联声纳浮标检测组,采用三浮标最小方差交叉定位技术, 完成了浮标声纳覆盖阵量测信号预处理。然后, 针对水下目标旋回运动的不同阶段, 提出了自适应随机Hough变换检测方法, 得到了初始检测航迹。最后, 通过对初始检测航迹进行点迹优化, 实现了水下目标检测。仿真结果表明,在小测角误差、复杂水声及低信噪比条件下, 该方法的平均检测概率达到60%以上, 整体性能优于现有权威检测方法水平。

Abstract:

Under the complex underwater acoustic conditions, to address the passive detection problem of underwater targets with typical motion patterns, an adaptive stochastic Hough transform-before-detection tracking method is studied to detect underwater cyclonic moving targets. Firstly, based on the characteristics of the underwater target's cyclic motion, the small rudder angle cyclic motion equation is deduced. Secondly, the preprocessing of the measurement signal of the buoy sonar coverage array is completed by constructing an adaptive correlation sonar buoy detection group and adopting the three-buoy minimum variance cross-location technology. Thirdly, an adaptive random Hough transform detection method is proposed for the different stages of the underwater target's cyclonic motion, and the initial detection track is obtained. Finally, the underwater target detection is realized by optimizing the initial detection track. The simulation results show that under the conditions of small angle measurement error, complex underwater acoustic and low signal to noise ratio, the average detection probability of the proposed method is more than 60%, and the overall performance is superior to the existing authoritative detection methods.
