致冷探测器在空空导弹中的应用

Cooled Detectors in Air to Air Missiles

热力学的三个热电效应，奠定了近代高效红外探测器致冷技术的理论基础。本文对多种致冷型与非致冷型空空导弹的性能进行了比较，阐述了致冷探测器在空空导弹中的应用，以及对高技术武器装备发展的深刻影响。

Based on the theory of thermoelectrical effect,cryocooling techni。ues of air to air missiles were described. A variety of air to air missiles with cooled or uncooled detectors were reviewed. Cryocoolers play an important role in missile seekers.Therefore,the type of cryocooler has an apparent influence on the performance of the missiles.
