遥感变化检测是指通过对不同时期同一区域的遥感图像进行比较分析,根据
图像之间的差异得到我们所需要的地物或目标的变化信息。现代遥感技术的飞速发展为变化检测提供了一种便捷的途径,遥感数据成为变化检测的主要数据源。 与可见光和红外遥感相比,微波遥感具有无可比拟的优点:微波能穿透云雾、雨雪,具有全天候、全天时的工作能力。二,微波对地物有一定穿透能力。三,采用侧视方式成像,覆盖面积大。正是这些优点,使得SAR 图像日益成为变化检测的重要数据源。
SAR 变化检测技术的需求日益广泛。目前,全球坏境变化加剧,城市急速发展,洪水、地震等自然灾害时有发生,这些都需要及时掌握相关动态信息,为相关决策部门提供支持,而SAR 的种种优点为快速响应提供了技术支持和应急保障。-Remote sensing change detection is through the same period of different regions of the same area of remote sensing images for comparative analysis, according to
The difference between the images gets the information of the changes in the objects or targets we need. The rapid development of modern remote sensing technology provides a convenient way for change detection, and remote sensing data become the main data source of change detection. Compared with visible and infrared remote sensing, microwave remote sensing has unparalleled advantages: microwave can penetrate the clouds, rain and snow, with all-weather, all day working ability. Second, the microwave has a certain ability to penetrate the ground. Third, the use of side view imaging, covering a large area. It is these advantages that make SAR images increasingly becoming important data sources for change detection. The following are the same as the
