摘要:

磁异常探测技术在水下航行器目标探测中具有重要应用价值。针对海浪噪声干扰下磁异常信号难以有效提取的问题,提出一种结合改进卡尔曼滤波与正交基分解的联合检测方法。首先,通过数值仿真构建任意航向下水下航行器的组合磁体模型,生成模拟磁异常信号;其次,结合有限深多层海水磁场噪声模型、海水电导率数据及海浪谱特性,构建叠加海浪噪声的磁异常探测数据;然后,采用改进的卡尔曼滤波算法有效抑制海浪噪声,增强信号质量;最后,利用正交基分解方法实现磁异常信号的高效检测。研究结果表明,在信噪比约为?15 dB、探测平台运动速度低于60 m/s的条件下,该方法能够维持较高的检测概率,验证了其在复杂海浪噪声环境下的鲁棒性。

Abstract:

Magnetic anomaly detection technology holds significant application value in target detection for underwater vehicles. To address the challenge of effectively extracting magnetic anomaly signals in sea wave noise interference, a joint detection method combining improved Kalman filtering and orthogonal basis decomposition is proposed. Firstly, a composite magnetic model of an underwater vehicle in arbitrary navigation is constructed through numerical simulation to generate simulated magnetic anomaly signals. Secondly, a magnetic anomaly detection dataset superimposed with sea wave noise is developed by integrating a finite-depth multilayer seawater magnetic field noise model, seawater conductivity data, and sea wave spectrum characteristics. Subsequently, an improved Kalman filtering algorithm is employed to effectively suppress sea wave noise and enhance signal quality. Finally, the orthogonal basis decomposition method is utilized to achieve efficient detection of magnetic anomaly signals. The results demonstrate that in conditions with a signal-to-noise ratio of approximately ?15 dB and a detection platform speed below 60 m/s, the proposed method maintains a high detection probability, verifying its robustness in complex sea wave noise environments.

Key words: magnetic anomaly detection, sea wave noise, improved Kalman filtering, orthogonal basis decomposition, complex marine environment
