SGLI火災プロダクトにおけるPost-launch版 火災検知アルゴリズムの提案

抄録

We propose a post-launch algorithm for the SGLI active fire detection products. Based on the pre-launch algorithm, some modification is made in order to work on the SGLI fire monitoring system. The main point of the modification is to apply statistical methods to the fire detection scheme, possibly improving the robustness of the algorithm performance. The post-launch algorithm was developed and evaluated using the SGLI data. It was clarified that this algorithm was able to detect obvious fire pixels with relatively higher accuracy, and the false alarms (false positives) were seen in burned-out sites and bright soils.
