Abstract

In order to analyze polarization characteristics of chaff jamming and improve capability of anti-chaff jamming of guidance radar based on polarization characteristics difference, chaff cloud model of different density, shape and distribution was established, and then, electromagnetic field numerical calculation method was introduced in calculation of chaff cloud polarization scattering characteristics. The calculation results show that the chaff cloud RCS is proportional to density, and satisfying the law that full-polarization is greater than copolarization and co-polarization is greater than cross-polarization. At the same time, four elements of the polarized scattering matrix are got. The research conclusions are of great significance for building of real simulation battlefield environment, conducting of radar polarization interference experiment and improvement of radar performance.

Key words： chaff cloud; co-polarization; cross-polarization; polarization matrix
