| 摘 要： | 为检测强杂波背景中的红外弱小运动目标，提出一种基于Power-Law检测器的目标检测新方法．利用图像中弱小目标经过时像素点灰度值有起伏变化这一特点，将其看作是一种弱瞬态信号，利用Power-Law检测器对瞬态信号良好的检测性能，实现对弱小运动目标的检测．仿真结果表明该算法能够可靠地检测出信杂比(SCR)大于1的弱小运动目标．

| Abstract: | A new algorithm based on the Power-Law detector is developed to detect a small moving target under heavy infrared background. Because the fluctuation of the gray-scale value of a pixel in an image occurs when a target passes by, this fluctuation can be viewed as a weak transient signal which can be detected by the Power-Law processor due to its advanced performance on transient signal detection. Experimental results show that the algorithm can reliably detect small targets with SCR larger than 1. |
