| 摘 要： | 研究了复杂背景下弱小目标在可见光CCD卫星传感器上的成像机理问题。弱小目标不易被卫星CCD传感器探测到,易被强大的噪声淹没,给检测提取带来了巨大的困难。从影响弱小目标成像的弥散因素入手,定量分析了大气、光学系统、探测器和传感器的振动等弥散因素对弱小目标的成像尺寸和成像强度的影响。在弥散成像的范围内,推导出了弱小目标与背景的对比度传输系数公式。通过航空试验进行了模拟验证,为其准确检测提取提供理论指导。

| Abstract: | This paper studies small target imaging mechanism in visual CCD sensor.It is difficult to detect small target for satellite visual CCD sensor,even if detected,small target is submerged in strong noises,which brings great difficulty for detection and segment of small target.This paper starts with the dispersion factor affecting the imaging of small target,analyzing the effect of atmosphere,optics system,detector and its vibration and other factors to image intensity and size in quantification.A contrast tran... |
