摘要
为了确保天基预警系统的探测能力,要求系统具有很强的弱信号目标检测与识别能力和实时预警能力。为了能够在复杂云层背景条件下,快速实时有效地检测出红外图像中的弱目标,本文提出了采用基于广义最大似然比准则的弱目标检测算法。通过实验验证,该算法能有效克服云层背景的影响,在目标信噪比很低的情况下可靠检测目标。
The detection capability of early-warning system requires that the system must have strong detection/discrimination and space-based identification capability of dim targets as well as real-time early warning capability.This paper studies the methods of detecting dim targets from infrared images rapidly and effectively in real-time under the background of complicated clouds conditions,and puts forward an algorithm of dim target detection based on the rule of generalized likelihood ratio test.Verified by experiments,the method can effectively overcome the affect of cloud background and reliably detect the targets with very low signal-noise ratio.
