Research progress on composite interference of infrared/millimeter smoke material and its extinction performance

Passive interference from smoke screen is an important part of optoelectronic countermeasure. With the rapid development of photoelectric weapons, the status of the smoke screen aerosol is increasing day by day, and multi- spectrum composite jammers have become the top priority of smokescreen passive interference technology. In order to promote the research and application transformation of smoke screen materials, understand the research status of composite interference materials and improve the jamming performance of smoke screens on infrared/millimeter wave band, this paper finishes the analysis of the system from the interference of material composition, extinction mechanism, problems and development trend under the condition of selecting composite interference of infrared/millimeter wave smoke materials as the main research object. The research results show that: the combined interference material and the integrated interference material have their own advantages and disadvantages. New types of composite interference materials with better composite interference effects and a complete range are constantly emerging. The status quo of the current research is mainly manifested in the different limitations of different smoke screen materials and the poor systemicity of the compound extinction mechanism. Smoke screen materials are generally developing in the direction of excellent dynamic characteristics, low cost, easy survival and environmental protection.
