Electromagnetic Computational Modeling and Bistatic Scattering Characteristics Analysis of Spherical Jammer Group

Bistatic radar is widely used in the military field with its good anti-jammer ability and accurate detection and identification ability. How to implement effective jammer for this kind of radar system has become a research hotspot at present. Due to the small scattering intensity and weak echo energy of j ammer monomer, it has no advantage in countering the bistatic radar. It is necessary to release multiple jammers to form a group to form strong scattering, so as to interfere with the bistatic radar to detect and recognize the target, so the study on the scattering characteristics of the jammer group is particularly important. Therefore, this paper takes the group composed of spherical monomer as an example, first of all, MATLAB and CST STUDIO SUITE (CST) are used for joint modeling, and then electromagnetic simulation calculation is carried out on the group of spherical jammer objects with different bands, different sphere sizes, different group densities and different group distributions to analyze the bistatic scattering characteristics under different parameters. The research results show that the four parameters will have different degrees of influence on the bistatic scattering characteristics of the spherical jammer group, which provides a theoretical basis and data support for parameter selection and airspace planning against the bistatic radar.
