文中针对空中红外弱小目标的特性，对其检测、识别方法进行讨论，提出一种背景预测的思想方法，并讨论其在空中红外目标的检测、识别等问题中的应用前景。文中附有作者利用这种思想编制的程序对空中弱小目标的单帧检测、识别的结果，该算法已移植到DSP硬件信号处理器上，并通过实验取得了很好的效果。
In this paper, according to the characteristics of weak infrared targets in air, the methods of detection and recognition are discussed. A method of background prediction is put forward and its application foreground in the detection and identification of aerial infrared targets is discussed. Attached to the article using the idea of the preparation of this program on the weak target of the single-frame detection, identification results, the algorithm has been transplanted to the DSP hardware signal processor, and achieved good results through experiments.
