在过去的15年里,美国国防部购置了5万多具采用通用组件的第一代热像仪,其中许多不能满足武器系统距离要求。为了提高现行红外热像仪的性能,美国开发了采用焦平面阵列的第二代热像仪,它们与第一代产品相比,体积缩小,而且有效观察距离至少增加1倍。另外,为了提高导弹的性能,焦平面阵列还被导弹寻的头采用,使导 Over the past 15 years, the U.S. Department of Defense has purchased more than 50,000 first-generation thermal imaging cameras with common components, many of which do not meet the requirements of weapon system distances. To improve the performance of current thermal imaging cameras, the United States has developed second-generation thermal imaging cameras that use focal plane arrays that shrink in size and at least double the effective viewing distance compared to the first generation. In addition, in order to improve the performance of missiles, the focal plane array is also used by missiles to find the head
