摘要
通过研究船舶航行产生的三类尾迹(表面波尾迹、湍流尾迹、内波尾迹)形成机制,以及深入分析尾迹的微波、热红外、声学以及光学特性以及尾迹气泡相关特征,从理论上寻求星载光学传感器探测舰船尾迹的适用性依据,满足充分挖掘卫星遥感监测海洋应用能力的目的。结论认为现实条件下运用星载合成孔径雷达最适合监测船舶尾迹,星载热红外传感器不适合探测船舶尾迹,而星载光学传感器作为一种重要的补充手段有着独到的优势。
The formation mechanism of the surface wave wake, turbulent wake, internal wave wake generated by moving ships were described to analyze the microwave, thermal infrared, acoustic and optical properties of wakes as well as related properties of wake bubbles. These works provide the applicability of space-borne sensors in detecting ship wakes theoretically, which fully meet the purpose of satellite remote sensing marine targets. The results show that the space-borne synthetic aperture radar is best suitable for monitoring the ship wake, while space-borne optical sensors may be an important supplementary means, but space-borne thermal in- frared sensor is not suitable.
