红外警戒系统目标识别方法的研究

Target Detection in IR Warning System

讨论了红外警戒系统目标识别的方法。由于目标和背景杂波在特征上既有区别又有相似之处，采用单一的识别手段无法达到满意的性能，只有在空间、时间和光谱域内采用多种手段，才能逐渐排除杂波，获取真正的威胁目标。

Mehtods of target detection method in IR warning systems are described. Because of the background clutter, only one approach is usually not powerful enough to detect targets. The most effective method is the one that takes spatial, spectral and temporal features into account to extinct the clutters and get clear target signals.
