Abstract

Abstract Sentinel-1 C-band radar data were applied for the first time to determine a nuclear test, its underground H-bomb explosion location and the affected zone in North Korea on September 3, 2017. The nuclear test location was found according to line-of-sight displacement images via its maximum value. In this research, three scenes of Sentinel-1B data acquired in descending orbits, one after and two before the event (the nuclear test date), were used to detect the nuclear test location. The nuclear test location was found northeast of the Punggye-ri nuclear test site (8 km) with the following geographic coordinates: 41°11′1.85″N, 129°13′28.86″E. It was revealed that only a pair of Sentinel-1В radar scenes from August 17 and September 10 have been successfully applied to detect nuclear test zones.

Sentinel-1 SAR数据在朝鲜核试验地点探测中的应用

2017年9月3日，首次应用Sentinel-1 c波段雷达数据对朝鲜进行核试验、地下氢弹爆炸位置和影响区域进行了确定。通过其最大值，根据视距位移图像找到了核试验地点。在本研究中，哨兵- 1b在下降轨道上获取的三个场景数据，一个在事件之后，两个在事件之前(核试验日期)，用于检测核试验地点。核试验地点位于丰溪里核试验场东北方向(8公里)，地理坐标为:41°11′1.85″N, 129°13′28.86″E。据悉，仅在8月17日和9月10日的两组Sentinel-1В雷达场景成功应用于核试验区探测。

期刊介绍： Canadian Journal of Remote Sensing / Journal canadien de télédétection is a publication of the Canadian Aeronautics and Space Institute (CASI) and the official journal of the Canadian Remote Sensing Society (CRSS-SCT). Canadian Journal of Remote Sensing provides a forum for the publication of scientific research and review articles. The journal publishes topics including sensor and algorithm development, image processing techniques and advances focused on a wide range of remote sensing applications including, but not restricted to; forestry and agriculture, ecology, hydrology and water resources, oceans and ice, geology, urban, atmosphere, and environmental science. Articles can cover local to global scales and can be directly relevant to the Canadian, or equally important, the international community. The international editorial board provides expertise in a wide range of remote sensing theory and applications.
