摘　　要：随着激光干扰技术在红外成像制导武器领域的深入应用,激光干扰效能和抗激光干扰技术的研究也日益被重视,它们与激光干扰模型研究也密切相关。为了构建高置信度激光干扰耀斑模型,首先分析了激光干扰的物理模型与全链路传输特性,在此基础上建立激光干扰耀斑理论模型,同时又分析了不同波长激光在大气传输中的影响规律、不同发散角随距离变化的辐照度变化规律,最后通过数字模拟仿真的结果与激光照射红外相机实验进行对比,验证了激光干扰耀斑模型与实验所产生激光干扰图像的一致性。With the application of laser jamming technology in the field of infrared imaging guidance weapons, the research of laser jamming effectiveness and anti-jamming technology are also paid more and more attention, and they are also closely related to the laser jamming model. In order to construct a high confidence laser jamming model, firstly, the physical model of laser jamming and the characteristics of full link transmission were analyzed, and a theoretical model of laser jamming spot was established. At the same time, the influence law of different wavelength laser in atmospheric transmission and the variation law of irradiance with different divergence angle with distance were analyzed. Finally, the results of laser illumination camera experiment and digital simulation were compared, and the coherence between the laser jamming solar flare model and the laser jamming spot was verified.
