机载红外热像探潜技术

Detection of submarines by air borne IR imaging system

分析了潜艇热尾流形成的原因和浮升的规律,论述了机载红外热成像系统的组成、工作原理与工作方式.对红外热成像系统在探潜中的信噪比进行了计算,还进行了潜艇模型热尾流的红外探测试验研究.理论计算和试验分析表明,具有高灵敏度的机载红外成像系统可以在一定的距离上探测到潜艇热尾流的存在,所以该方法可用于反潜探测.

The formation and floating of the thermal wake from submarines were analyzed. The components and working principles and modes of aircraft-born IR imaging system were expounded. The signal-to-noise ratio of IR imaging system in detecting submarines was calculated. And IR detecting experiments for the thermal wake of submarine＇s models were carried out. After the calculation and a- nalysis, we get the conclusion that the air borne IR imaging system with high sensitivity can detect submarines＇ thermal wake at some distance. And this method can be adapt to application in antisubmarine detection.
