“全球鹰” 光电探测系统 激光干扰 饱和阈值 Global Hawk photoelectric detection system laser interference saturation threshold
摘要
近年来搭载先进光电侦察系统的“全球鹰”无人机严重威胁我沿海重要目标的保密安全。针对其光电侦察系统具有可见光和红外探测器双模块工作的特点,提出了采用强激光进行追踪干扰的对抗方法,并理论分析了电饱和效应对光电探测器激光干扰阈值的影响,最后通过模拟实验和光谱响应曲线理论计算得出了强激光干扰“全球鹰”可见光和红外探测器的光谱饱和阈值曲线。
Abstract
In recent years, the security of our important coastal military targets is severely threatened by Global Hawk, the unmanned aerial vehicle(UAV) carrying advanced photoelectric detection system. As the photoelectric detection system works in double mode, i.e. visible light mode and infrared mode. A countermeasure of tracking interference is proposed by high intensity laser. Moreover, the factors of electric saturation affecting the interference threshold of the photoelectric detection system are theoretically analyzed. Finally, the saturation threshold spectrums of the visible light and infrared detectors of Global Hawk are analyzed through simulation experiment and spectral response curve calculation.
