Electrodynamic simulation of transformation of wave modes in an H-plane waveguide transition is performed. The influence of different design versions of such a junction on the magnitude of excitation of higher-order modes is analyzed. Variation in the attenuation level of higher-order modes as a function of the chosen length of the transition is shown. © 2013 Pleiades Publishing, Ltd.

An H-plane optical distribution system for formation of a five-beam radiation pattern of active phased antenna arrays is proposed and analyzed. The distribution system is analyzed in time domain, which allowed obtaining the results on transient processes in this system. © 2013 Pleiades Publishing, Inc.

The paper presents calculation results obtained for the laser landing system (LLS) efficiency on the base of determining minimum required scattered radiation fluxes from fixed extended landmarks (FELs) which are LLS indicators in the case of visual FEL detection in real operational conditions. It is shown that the minimum required powers for a reliable detection of course glide beams in night conditions from distances L ≈ 1.0–1.6 km at meteorological visibility Sm = 800 m are Pmin = 0.5 W for λ = 0.52 and 0.64 µm for deviations from the glide path to the angle φ = 0°–5°. In twilight conditions, green and red laser beams are visible from distances L = 1–1.2 km. The performed calculations corroborated the possibility of creating a new generation laser-based LLS capable of ensuring aircraft landing in conditions of International Civil Aviation Organization (ICAO) category 1. © 2016, Pleiades Publishing, Ltd.
