基于磁电信息融合的海上目标探测方法

Maritime Target Detection Based on Magnetoelectric Information Fusion

摘要:

单一探测手段在海上目标探测任务中存在探测效率低、虚警率高的缺陷。为有效提高传感器对海上目标探测的探测能力，降低虚警率，提出了一种基于目标磁场、电场数据的融合探测方法，该方法在磁电数据能量检测的基础上，利用 Pearson 相关系数对证据来源的相关性进行评价，能够修正由环境干扰、传感器异常等因素带来的不稳定性。在海上试验平台，将提出的磁电融合方法与传统单一静磁探测方法对比，明显降低了虚警率，验证了方法的有效性。

Abstract:

Single detection method has the defects of low detection efficiency and high false alarm rate in marine target detection. In order to improve the detection ability of sensors and reduce the false alarm rate，a fusion detection method based on target magnetic field and electric field data is proposed. Based on the energy detection of magnetoelectric data，this method uses Pearson correlation coefficient to evaluate the correlation of evidence sources，which can correct the instability caused by environmental interference，sensor anomaly and other factors. On the sea test platform，the proposed magnetoelectric fusion method is compared with the traditional single magnetostatic detection method. Test results show that the proposed method can significantly reduce the false alarm rate and it is effective.
