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.
