近年来,世界许多地方地震多发,利用卫星监测乃至预报地震,已成为研究的重要领域。目前,世界各国监测地震的主要手段是地面台站观测。受观测环境、生活环境等诸多客观条件的限制,在国境边界、海洋、高山、原始森林等地区建观测台比较困难,现有的地面观测台站受干扰也越来越严重,这些都会导致地震监测区域出现空白点和观测资料不足。对地观测卫星具有全天候、全天时、全球性、周期
In recent years, earthquakes have occurred in many parts of the world and the use of satellite monitoring and even earthquake prediction has become an important area of research. At present, the main means of monitoring earthquakes in various countries in the world is the observation of ground stations. Due to many objective conditions, such as the observation environment and the living environment, it is difficult to build observatories in border areas, oceans, alpine regions and primeval forests, and the existing terrestrial observation stations are more and more interfered. All of these will lead to earthquakes Blank points in the monitoring area and insufficient observation data. Earth observation satellites have all-weather, all-day, global, cycle
