Abstract: The study of passive jamming electromagnetic scattering in highly adversarial environments has always been an important topic in the fields of computational electromagnetics, electric countermeasure and battlefield digital twinning. In-depth research on this issue serves as a critical theoretical foundation for future battlefield red-blue confrontation modeling, equipment design optimization, and tactical upgrades. Therefore, in response to the demands of generating new combat capabilities, it is of great significance to summarize and analyze the current state of research on typical passive jamming electromagnetic scattering. A highlight on the progress of electromagnetic scattering from typical passive jamming is presented. Current research on electromagnetic scattering modeling of passive jammers can be divided into four main aspects: scene construction, scattering calculation, experimental validation, and effectiveness evaluation. Research on geometric modeling focuses on the dynamic coupling effects between jammers and the environment. Scattering calculations for passive jammers primarily concentrate on large-scale scene partitioning and coupled scattering computation. Experimental studies on passive jamming scattering mostly revolve around controlled experiments and theoretical research on combined indoor and outdoor field testing. Effectiveness evaluation of jamming mainly targets optimized jammer design and deployment strategy formulation. At present, research on the integration of passive jammers with the environment still faces challenges such as low fidelity in scene construction, inefficient simulation computations, incomplete theoretical systems for experimental validation, limited effectiveness evaluation methods, and insufficient levels of intelligence. These issues constrain the development and enhancement of new combat capabilities. Based on existing research, this paper looks ahead and proposes that future efforts include: Combine multi-physics coupling methods to achieve high-precision geometric and scattering modeling of passive jammers integrated with backgrounds; Introduce intelligent evaluation methods to optimize jammer effectiveness assessment and design; Incorporate controlled testing techniques into indoor and outdoor field experiment designs to achieve integrated research on radar signature measurement and analysis of passive jammers.
