- Аннотация: The results of simulation of the bistatic radar cross-section (RCS) of perfectly conducting bodies based on electromagnetic near-field computations are presented. The relevance of the topic is dictated by the need to measure bistatic RCS in anechoic chambers. Near fields are simulated using the FEKO software package, while only a part of the finite cylindrical scanning surface is considered, which does not completely cover the object under study. We have considered two methods for obtaining bistatic RCS patterns based on the fields calculated on the scanning surface using the Stratton–Chu formulas and by expanding the electromagnetic field in terms of cylindrical waves. The possibility of obtaining bistatic patterns in a given range of bistatic angles during measurements on the specified scanning surfaces with a radius on the order of 3–4 wavelengths is studied. The results of the both methods are compared. The scanning surface height required for the specified accuracy of the RCS pattern is determined for the scanning surface completely encircling the cylinder in the azimuthal plane.
