In this paper, approximate formulas are obtained for the monostatic and bistatic diagrams of radar cross-section of waveguide Van-Atta array considering excitation and propagation of higher types of waves in plumbings. Their contribution to the scattered field is studied. The required number of higher types of waves and their propagation conditions are estimated to ensure the widest possible monostatic...
The paper presents results of Van Atta Array scattering characteristics research. The research was done for an array consisted of a set of parallel-plate waveguides with apertures located on the same plane for two different configurations: 1) the apertures are separated with impedance flange (Figure 1) and 2) the apertures are separated with semi-infinite parallel-plate waveguides - excited waves...
