| 摘 要： | 当红外预警系统对低空飞行的运动目标进行检测时,由于云杂波的存在,系统的检测性能会受到严重影响。分析了云层背景下目标和云层在探测器上的时间响应特性,建立了四种类型的像素点时域模型。并以这四种时域模型为基础,提出了云层背景下点目标的时域检测算法。理论分析和实验结果表明,新算法能有效检测出各种云层背景下的点目标。

| Abstract: | When the infrared early warning system is detecting a moving target at low altitude,its detection performance will decrease significantly because of cloud.Target and cloud's temporal profiles on detector are studied,and four temporal models are built.Based on these models,a temporal detection algorithm is proposed.According to the theoretical analysis and experimental resultsal,the new algorithm can effectively detect the point target in different cloud backgrounds. |
