| 摘 要： | 海洋环境对舰艇的作战效能具有重要影响,特别是海洋锋等海洋中尺度现象将导致水下声传播产生畸变从而严重影响舰艇的声学探测。研究了黑潮锋区海洋环境的特点,提出了利用趋势面分析得到黑潮锋区温度场的大面分布以及黑潮锋的变化趋势,探讨了计算温度场坡度、提取黑潮锋空间分布特征的方法,分析结果表明了该方法的有效性。

| Abstract: | The ocean environment has an important influence for the navy operational efficiency,especially in the meso-scale ocean front area which makes obvious impact of sonar detection by changing the sound ray trace.According to the feature of Korushio front,the extracting method of Kuroshio front characteristics is proposed by using the slope analysis and GIS.Simulation results of front yearly various characteristics shows that the method is practicable |
