为能及时发现火情,准确定出火源方位、距离,同步监视火势发展及森林环境情况,需要有与之相适应的仪器。但是,目前我国基本上还是采用防火塔加望远镜的方法在高山上监测林火。由于这种方法受天气等因素影响很大,特别是仪器本身的功能及水平低,不能很好完成监测林火的目的。尽管国外有应用卫星遥感技术、 In order to discover the fire in time, accurately determine the orientation and distance of the fire source, and simultaneously monitor the development of the fire and the forest environment, we need instruments that are suitable for it. However, at present, our country basically adopts the method of fire tower and telescope to monitor forest fire on the mountain. Because this method is greatly affected by the weather and other factors, especially the function and level of the instrument itself is low, can not well complete the purpose of monitoring forest fire. Although there are foreign applications of satellite remote sensing technology,
