Abstract:

The scattering behavior for a collection of thousands of linear dipoles at resonance has long been a subject of study for passive electronic countermeasures (ECM) against pertinent threat radar systems. Previously, the echo area of the radar cross section (RCS) of a chaff cloud has been calculated by multiplying the number of dipoles by the so-called "tumble average RCS" of a single dipole. Estimates based on this simple model have been poor. In this study a rigorous mathematical model based on the sinusoidal reaction formulation will be solved by the method of moments of the Galerkin type. Using a snap-shot model of various chaff geometries, possibly from a fractal based generator, both the mono-static and bi-static scattering signatures will be statistically characterized. Furthermore, the effects of aspect angle on chaff signatures will be quantified, and the correlation between the chaff signatures obtained at different look angles will be established.
