摘　　要：基于激光干扰的激光定向红外对抗系统是目前对抗第1代、第2代点源制导红外导引头最有效的手段。然而,随着红外制导技术的持续发展,最新一代红外成像导引头用目标更加稳定、更丰富多维的图像信息取代了简单的调制信号来进行抗干扰设计,大幅提升了其对抗激光干扰的能力,这就使对激光干扰红外成像导引头的效能研究变得十分必要。通过分析激光成功干扰红外成像导引头的条件和能量要求,指导激光定向对抗系统进行干扰性能提升,最终达到对抗红外成像制导导弹的目的。首先阐述了红外成像型导引头和激光干扰的工作原理;然后分析得到了激光成功干扰红外成像型导引头的条件,并通过试验,完成对激光干扰成像型导引头的效能分析,得到激光成功干扰成像型导引头的能量等要求;最后对未来的技术发展方向进行了阐述。The laser countermeasures system is the most effective method currently available to counter 1 st and 2 nd generation point-type infrared guided seekers.However,the latest infrared imaging seekers use stable and multi-dimensional images instead of simple point-modulated information to guide the missile,making it not susceptible to laser countermeasures.So,it is necessary to investigate the effectiveness of laser countermeasures imposed on infrared imaging seekers and obtain the requirements of successful countermeasures,which could help the laser directional infrared countermeasure system to be designed specifically to handle the threat from infrared-imaging guided missiles.The paper first introduces the working principles of infrared imaging seekers and laser coutermeasure.Then,the effectiveness of laser countermeasurs against infrared imaging seekers is analyzed,and the requirements of successful countermeasures are derived based on the experimental results.In the end,the paper illustrates the future development of laser countermeasures.
