烟幕遮蔽和干扰效果评价方法研究

Assessment Methods of Smoke Screening and Interference Effect

烟幕是一种应用较为广泛的无源干扰手段,在对抗各类光电侦察和光电制导装置方面发挥着重要作用。烟幕遮蔽和干扰效果评价是评估光电对抗效果、进行战术部署的重要依据,是烟幕技术的重要研究内容。针对目前评价方法杂、评价方法选用无据可依的现状,在综述当前烟幕遮蔽和干扰效果评价研究现状的基础上,从烟幕本身的遮蔽性能、被干扰对象工作性能、烟幕干扰前后图像质量受影响的角度,系统归纳了能较好地描述烟幕遮蔽和干扰效果的主要评价指标及其测试方法,指出了方法的优缺点、适用场合与局限性,并对下一步研究工作和发展方向进行了展望。

Smoke screening is an effective passive interference countermeasure that is extensively used to counter various types of electro-optical reconnaissance and guided weapons.Evaluating smoke screening and its interference effects is crucial for assessing photoelectric countermeasures and tactical deployment,which constitutes the main focus of research within the context of smoke screen technology.Current evaluation methods are complex and lack a solid foundation;therefore,we proposed evaluation methods to better describe the smoke screening and interfering effects,based on a review of existing evaluation methodologies.These methods focus on the shielding performance of the smoke screening,the operational states of the interfered targets,and the changes in the image quality before and after smoke screening.Moreover,we discussed the proposed method’s advantages and disadvantages,application occasions,and limitations.Finally,this paper outlines future research directions and emerging trends concerning the effects of smoke screening.
