Radar cross section of arbitrarily shaped bodies of revolution
Article Abstract:
Surface integral equation (SIE) formulation and method of moments are used to determine the surface currents and, consequently, the radar cross section (RCS) of a homogeneous, arbitrarily shaped dielectric body of revolution (BOR). A Fourier series expansion of the angle of rotational symmetry of the BOR enables the efficient solution of RCS scattering because it is reduced to a one-dimensional problem and allows the use of method of moments calculations. Comparison of SIE and approximate integral equation (AIE) formulations for the evaluation of the RCS of a composite dielectric and conducting BOR show that AIE is more efficient in computational time and storage. Procedures and equations for the RCS evaluation methodology are described.

Radar cross section of complex targets
Article Abstract:
The Radar Cross Section Technology division of Boeing Aerospace Co (Seattle, WA) has developed the RECOTA (return from complex target) software to calculate the radar cross section (RCS) of complex targets. The software uses a computer-aided design (CAD) package to model such targets in terms of facet and wedge components. RECOTA utilizes the theory of physical optics, physical theory of diffraction, ray tracing, and semi-empirical methodologies to evaluate target object RCS, including shadowing effects, facet and wedge scattering, multiple scattering, and returns from discontinuities. Evaluation of RECOTA functioning show that its predictions of target geometry are close to actual measurements.
