摘要
激光定向干扰严重影响红外成像系统的应用效能。针对红外成像系统面临的激光定向干扰问题,基于分光成像技术,提出了利用轮转滤光片的方法,将3μm~5μm中红外波段继续划分成三个子波段进行分光成像,由于激光能量仅集中在某一个子波段内,其他子波段能对目标正常成像,因此可以有效对抗激光干扰。实验结果表明波段分光抗干扰技术具备可行性,可为工程化应用提供参考。
Laser directional jamming seriously affects the application efficiency of infrared imaging systems.In response to the problem of laser directional jamming faced by infrared imaging systems,a method using rotating filters is proposed based on spectral imaging technology.The 3 μm~5 μm mid-infrared laser band is further divided into three sub-bands for spectral imaging.Since the laser energy is only concentrated in a certain sub-band,the other sub-bands can image the target normally to counter the laser jamming.The experiment shows that the wave-band splitting anti-laser directional jamming technology is feasible and can provide reference for engineering application.
