高速飞行和低空突防任务所遇到的更为恶劣的环境,已要求研制新的遮盖机载电磁传感器(例如:前向寻的红外传感器和雷达)的“窗”口材料。机载高能激光辐射的可能出现,使解决这一问题更为困难,因为它要求窗口材料具有特别高的透射率。用于电磁传感器和激光器的窗口材料,正面临着座舱罩遇到的许多同样问题——气 The harsher conditions encountered by high-speed flying and low-altitude penetration missions have required the development of new “window” materials that cover on-board electromagnetic sensors such as forward-looking infrared sensors and radars. The possible occurrence of on-board high-energy laser radiation makes it more difficult to solve this problem because it requires window materials with particularly high transmissivity. Window materials for electromagnetic sensors and lasers are facing many of the same problems encountered with canopy
