主动红外尽管主动红外容易被对方探测,但至今还有很多产品仍然装在坦克上,不过很快将被热成象装置所代替。热成象实现扫描的方法有两种——机械扫描和电子扫描。电子扫描的优点是可以减少机械部件的数量,不过,产生的图象经常不太理想。首先使用热成象技术的是侦察飞机。侦察飞机用红外扫描装置搜索机下的地面,当飞机向前飞行时,扫描装置扫描到一条条连续的地带,从而逐步形成一张地面热图。同样,飞机内的前视红外装置扫描飞机前面的一条地带, Active Infrared Although active infrared can easily be detected by each other, so far there are still many products are still mounted on the tank, but will soon be replaced by thermal imaging device. There are two ways to accomplish scanning by thermal imaging - mechanical scanning and electronic scanning. The advantage of electronic scanning is that the number of mechanical components can be reduced, however, the resulting images are often less than ideal. First, the use of thermal imaging technology is reconnaissance aircraft. Reconnaissance aircraft use infrared scanners to search the ground beneath the aircraft. As the aircraft flies forward, the scanning device scans a continuous strip of land, gradually forming a ground heat map. Similarly, the forward-looking infrared device inside the aircraft scans a strip in front of the aircraft,
