| 摘 要： | 为了有效地从风浪背景中检测舰船水压场信号，在对大量实测海浪水压场数据和舰船水压场数据分析的基础上，对海浪水压场信号的特性进行了研究，发现海浪水压场信号可用AR模型对其进行描述．从而对海浪水压场信号建立AR模型，计算AR模型的反射系数并提取其欧氏距离作为特征，采用滑动检测法对信号进行实时检测．通过大量实测数据检验其有效性，结果表明，该算法简单，能较好的检测目标信号．

| Abstract: | In order to effectively detect the ship hydrodynamic pressure field signal from a high sea state,a large of real ocean wave hydrodynamic pressure field signal has been studied,it has been confirmed that the ocean wave hydrodynamic pressure field signal obeys the auto-regression model in a short time.Then a real-time target detection method has been proposed based on the Euclidean distance between the reflection coefficients of the ship hydrodynamic pressure field signal and the reflection coefficients of th... |
