摘　　要：文章讨论了非制冷红外热像系统的总体性能,分析了影响该热像仪综合性能的主要原因,提出性能改善的基本方法,介绍了独特的虚拟电子微扫技术的基本原理及实现方法。针对远处小目标红外图像的有用信息进行了放大处理。采用DSP+FPGA的架构在硬件平台上得到了实现。实验证明:虚拟电子微扫技术有利于识别目标,效果良好。In the paper, the capability of the uncooled thermal imaging system is discussed. The primary reason affecting the integrated capability of thermal system and the basic method of increasing the capability are analysed. The basic principle and the realizing method of the original dummy electronic micro scanning technique are introduced. The useful information for infrared image of the far small target is zoomed out. The real-time image processing is engaged in by using DSP ＋ FPGA structure. Results show that the dummy electric micro-scanning technique is propitious to recognize target, and the effect is well.
