四、国外森林红外探火进展情况美国从1962年开始着手下述三方面研究: 1. 研究最佳的机载林火红外探测系统; 2. 研究不同林型不同探测角度下,发现林火的概率; 3. 发展林火探测飞行的巡航程序(包括使用服务)。红外扫描相机作为军事侦察用,美国五十年代就装在U-2间谍飞机上,用于探测林火则是军用向民用渗透的结果。红外探火的发展历经了向军备部门借用到改用,最后专门设计专
Fourth, the progress of the foreign forest infrared detection Fire from 1962 the United States embarked on the following three aspects: 1. To study the best airborne forest fire infrared detection system; 2. To study different forest types of detection angle, found that forest fire Probability; 3. Develop cruise procedures for forest fire detection flights (including the use of services). Infrared scan cameras for military reconnaissance purposes, the United States installed on the U-2 spy plane in the 1950s, is used for detecting forest fire as a result of military infiltration to the civilian. The development of infrared fire detection after borrowing to the military sector to switch to the last specialized design
